2. Simplicity on the far side of complexity: optimizing nitrogen for wheat in increasingly variable rainfall environments

Author: Z Hochman and F Waldner

Abstract: The increasingly chaotic nature of rainfall in semi-arid climates challenges crop growers to balance nitrogen fertiliser inputs for both food security and environmental imperatives. Too little nitrogen restricts yields and runs down soil organic carbon, while too much nitrogen is economically wasteful and environmentally harmful. The degree to which crop-water and crop-nitrogen processes combine to drive yields of rainfed wheat crops is not well understood or quantified. Here we investigate two comprehensive Australia-wide data sets, one from commercial wheat growers’ fields and the other from systematic simulation of 50 sites by 15 years using a comprehensive mechanistic cropping system model. From these data, we derived a simple model combining water use with available nitrogen and their interaction. The model accounted for 73% of the variation in the simulated yield data and 46% of the variation in the growers’ yield data. We demonstrate how the simple model developed here can be deployed as a tool to aid growers’ in-crop nitrogen application decisions.

Abstract: The tau lepton lifetime is measured with the L3 detector at LEP using the complete data taken at centre-of-mass energies around the Z pole resulting in tau_tau = 293.2 +/- 2.0 (stat) +/- 1.5 (syst) fs. The comparison of this result with the muon lifetime supports lepton universality of the weak charged current at the level of six per mille. Assuming lepton universality, the value of the strong coupling constant, alpha_s is found to be alpha_s(m_tau^2) = 0.319 +/- 0.015(exp.) +/- 0.014 (theory). The tau lepton lifetime is measured with the L3 detector at LEP using the complete data taken at centre-of-mass energies around the Z pole resulting in τ τ =293.2 ± 2.0 (stat) ± 1.5 (syst) fs . The comparison of this result with the muon lifetime supports lepton universality of the weak charged current at the level of six per mille. Assuming lepton universality, the value of the strong coupling constant, α s is found to be α s ( m τ 2 ) = 0.319 ± 0.015 (exp) ± 0.014 (theory).

Abstract: A determination of the partial width Γc̄ of the Z0 boson into charm quark pairs is presented, based on a total sample of 36 900 Z0 hadronic decays measured with the DELPHI detector at the LEP collider. The production rate of cc events is derived from the inclusive analysis of charged pions coming from the decay of charmed meson D*+-→D0π+ and D*-→D̄0π- where the π± is constrained by kinematics to have a low pT with respect to the jet axis. The probability to procedure these π± from D*± decay in cc events is taken to be 0.31±0.05 as measured at √S = 10.55 GeV. The measured relative partial width Γ∞/Γh = 0.162± 0.030(stat.) ± 0.050(syst.) is in good agreement with the standard model value of 0.171. Together with our previous measurement of the total hadronic width Γh this implies Γ∞ = 282 ± 53 (stat.) ± 88 (syst.) MeV., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: Bose-Einstein correlation between pairs of like-sign charged particles produced in e+e- annihilations near the Z0 peak have been studied using data taken with the DELPHI detector at LEP. An enhancement is found in the production of pairs of identical pions of similar moments, with respect to a reference sample. Under the hypothesis that the pions are emitted by a spherically symmetrical source with gaussian density, the data indicate a radius of the source of r = 0.62±0.04(stat.)±0.20(syst.) fm. The large systematic uncertainty reflects the sensitivity of r to the choice of the reference sample, 0, info:eu-repo/semantics/published

Abstract: We have searched for excited states of charged and neutral leptons, e∗, μ ∗ , τ ∗ and ν ∗ , in e+e− collisions at s =130 using the OPAL detector at LEP. No evidence for their existence was found. With the most common coupling assumptions, the final states from excited lepton pair production include l+l−γγ and l+l−WW (with the subsequent decay of the virtual W bosons). From the analysis of these final states, 95% confidence level lower mass limits of 66.5 GeV for e∗, 66.8 GeV for μ ∗ , 65.3 GeV for τ ∗ , 66.2 GeV for ν e ∗ , 66.5 GeV for ν μ ∗ and 64.7 GeV for ν τ ∗ are inferred. From the analysis of γγ final states with missing energy and using alternative coupling assignments which permit photonic ν ∗ decays, a 95% confidence level lower mass limit of 65.0 GeV for each ν ∗ flavour is inferred. From the analysis of the l+l−γ, acoplanar lepton pair, and single γ final states expected from excited lepton single production, upper limits on f Λ (ratio of the coupling to the compositeness scale) are determined for excited lepton masses up to the kinematic limit.

Abstract: Using data accumulated by DELPHI during the November 1995 LEP run at 130–136 GeV, searchs have been made for events with jets or leptons in conjunction with missing momentum. The results are interpreted in terms of limits on the production of neutralinos, scalar leptons, and scalar quarks.

Abstract: From the data collected by DELPHI at LEP in autumn 1995, the multiplicity of charged particles at a hadronic energy of 130 GeV has been measured to be 〈nch〉 = 23.84 ± 0.51 (stat) ± 0.52 (syst). When compared to lower energy data, the value measured is consistent with the evolution predicted by QCD with corrections at next-to-leading order, for a value αs(130 GeV) = 0.105 ± 0.003 (stat) ± 0.008 (syst).

11. 2D periodically ordered states of vortices–antivortices and skyrmion-like excitations in planar up to isotropic heisenberg classical spin arrays

Author: F. Waldner
Subjects: Physics, Planar, Condensed matter physics, Spins, Heisenberg model, Skyrmion, Quantum mechanics, Isotropy, Symmetry group, Condensed Matter Physics, Spin (physics), Symmetry (physics), Electronic, Optical and Magnetic Materials
Abstract: In 2D classical spin arrays subject to planar Heisenberg interaction Jxy, periodic metastable states of vortex–antivortex pairs will be described. In the unit cell of 2n×2n spins with the symmetry of planar group P4, two vortices and two antivortices are arranged. Their pair energy increases nearly logarithmically with pair distance n. In contrast, for isotropic interaction J the excitations are half-skyrmion-like and their pair energy is ≈4πJ(1–1.02/n2), hence 4πJ in the continuous limit as for a single skyrmion. A collapse is prevented due to the increase of the mean energy per spin for decreasing distance n.

Abstract: A measurement of B meson lifetimes is presented using data collected from 1991 to 1993 by the DELPHI detector at the LEP collider. Samples of events with a D meson and a lepton in the same jet are selected where$\bar D^{^0 } \ell ^ + $ and D*l+ events originate mainly from the semileptonic decays of B+ and B0 mesons, respectively. From the reconstructed B decay length and the estimated B momentum, taking into account the dilution due to B decays into$\bar D^{^{**} } \ell ^ + v$, the following B meson lifetimes and lifetime ratio are measured: $$\begin{gathered} \tau (B^ + ) = 1.61_{ - 0.16}^{ + 0.16} (stat.) \pm 0.12(syst.) ps \hfill \\ \tau (B^0 ) = 1.61_{ - 0.13}^{ + 0.14} (stat.) \pm 0.08(syst.) ps \hfill \\ \tau (B^ + )/\tau (B^0 ) = 1.00_{ - 0.15}^{ + 0.17} (stat.) \pm 0.10(syst.) \hfill \\ \end{gathered} $$ and an average lifetime of B+ and B0 mesons is obtained: $$\tau (B) = 1.61_{ - 0.07}^{ + 0.08} (stat.) \pm 0.05(syst.) ps$$

Abstract: A sample of events enriched in bb̄ quark pairs was selected in the data recorded by the DELPHI experiment at LEP during 1992 and 1993, by the presence of secondary decay vertices from short-lived particles. Using this sample, the average multiplicities of Ks0, K±, p(p̄), Λ(View the MathML source) and of charged particles in bb̄ events have been measured, distinguishing the component from fragmentation and the component coming from the decay of b-hadrons. The measurement of the average charge multiplicity in bb̄ events was used to compute the mean fractional beam energy carried by the primary b-hadron, and the difference in charged particle multiplicity between bb̄ events and light quark (uū, dd̄, ss̄) events.

Abstract: The production of multihadronic states in γγ collisions at LEP has been studied with the DELPHI detector. The analyzed data correspond to an integrated luminosity of about 32pb−1, collected in the LEP runs of 1990–1992. Minimum bias data and a sample of events with jets at highpT have been selected under the requirement that no scattered electron or positron is observed. The two data sets have been compared to Monte Carlo predictions. The non-perturbative contribution described by the vector meson dominance Model and direct$q\bar q$ production from pointlike photons described by the quark parton model were found to be insufficient to reproduce the data. It has been necessary to include a third interaction component, which is due to perburbative hard scattering of the partonic constituents of the photon. Several parametrisations of the quark and gluon densities of the photon have been tested. The interplay with the cut in jet transverse momentum, which is necessary for the separation of the perturbative and non-perturbative regions, is discussed. The data favour parametrisations with rather soft partonic content of the photon.

Abstract: A total of about View the MathML source decays have been analyzed to measure the View the MathML source mixing probability. Two different b tagging techniques have been used: events with two leptons and events with one lepton and one Λ. From a combination of the two methods the average mixing parameter, χ, was determined to be (12.1±1.6(stat.)±0.4(syst.)±0.4(model)%.

Abstract: The total and the differential cross sections for the reaction e+e− → γγ(γ) have been measured with the DELPHI detector at LEP using an integrated luminosity of 36.9 pb−1. The results agree with the QED predictions and consequently there is no evidence for non-standard channels with the same experimental signature. The lower limits obtained on the QED cutoff parameters are Λ+ > 143 GeV and Λ− > 120 GeV, and the lower bound on the mass of an excited electron with an effective coupling constant λγ = 1 is 132 GeV/c2. Upper limits on the branching ratios for the decays Z0 → γγ, Z0 → π0γ, Z0 → ηγ and Z0 → γγγ have been determined to be 5.5 × 10−5, 5.5 × 10−5, 8.0 × 10−5, and 1.7 × 10−5 respectively. All the limits are at the 95% confidence level.

17. An elementary model of non-exponential decay. I. Description of model and comparison with other models

Abstract: The motivation of this work is to search for an elementary common physical mechanism for the non-exponential decay observed in a large number of disparate phenomena. Probably the most elementary assumption is an initial Poissonian distribution of activation energies E with each fraction decaying independently according to an Arrhenius rate r(E) approximately exp(-E/T). Despite this drastic oversimplification, this elementary model will account for a large variety of observed shapes of decay, ranging from nearly exponential to power law and nearly logarithmic functions. The fundamental feature that governs the shape is the ratio E/T, denoted 1/b, of the mean E at temperature T. Analysing limited experimental data sets is also easy due to the closed form of the resulting normalized decay curves g(b, tau )=b tau -b gamma (b,tau/), where tau =r0t is the time t normalized by the rate r0. The incomplete gamma function gamma (b, tau )= integral 0tau sb-1e-sds is an important correction of the power law tau -b In an alternative interpretation, this decay form g(b, tau ) could also be considered as generated by a b-dependent form of an effective barrier energy Ueff(g) increasing as a function of the decaying normalized observable g. In this paper the forms g(b, tau ) and Ueff(g) are evaluated, displayed and compared with In a separate paper the widespread applicability of the form g(b,tau/) will be demonstrated by interpreting various types of measured data using individual established temperature dependencies and by treating the 'ageing' or 'memory' effect.

Abstract: An analysis of the production of the Λ baryon in the hadronic decays of the Z0 is presented, based on about 993K multihadronic events collected by the DELPHI detector at LEP during 1991 and 1992. The differencial cross section of the Λ and the correlations between Λ and View the MathML source produced in the same event are compared to current models, based both on string fragmentation and on cluster decay. The predictions of the string fragmentation model are found to give satisfactory agreements with the data, clearly better than those of the cluster model.

Abstract: A study of inclusive production of the meson resonances ρ0, K*0 (892), f{hook}0 (975) and f{hook}2 (1270) in hadronic decays of the Z0 is presented. The measured mean meson multiplicity per hadronic event is 0.83 ± 0.14 for the ρ0 0.64 ± 0.24 for the K*0 (892), 0.10 ± 0.04 for the f{hook}0 (975) in the momentum range p > 0.05pbeam (xp > 0.05) and 0.11 ± 0.05 for the f{hook}2 (1270) for xp > 0.1. These values and the corresponding differential cross sections ( 1 σhadr) dσ dxp for the vector mesons are in good agreement with the predictions of the JETSET 7.3 PS and HERWIG 5.4 models. The f{hook}2 (1270) production is overestimated by HERWIG but its xp-shape is correctly reproduced. The measured ratios of the production cross sections σ(f{hook}2(1270)) σ(ρ0) = 0.22 ± 0.08 and σ(f{hook}2(1270)) σ(f{hook}0(975)) = 3-1 +7 for xp > 0.1 are consistent with the results obtained in hadronic reactions. © 1993.

Abstract: Nonlinear antiferromagnetic resonance observed by the parallel pumping technique in anisotropic materials exhibits a rich temporal behavior of the absorbed microwave power. When pumped well above the instability threshold, this involves fractal dimensions up to around 5. The basic physical behavior can be described with models that account for the interaction of n excited spin-wave modes. We report on simulations based on the 2n-dimensional stroboscopic model that allows an analytic integration of the (classical) spin motion between the strobing times. For three coupled spin-wave modes (n=3) we find two positive Lyapunov exponents indicating hyperchaotic behavior. The transitions from chaos to hyperchaos, which are observed upon variation of two different control parameters, can clearly be interpreted in terms of excited modes that actively contribute to the spin dynamics. Four coupled modes yield an even stronger chaos with three positive Lyapunov exponents. Moreover, we characterize our system by calculating spectra of local expansion exponents.

Abstract: The total and differential cross-sections for the reaction e+e- → γγ(γ) are measured at centre of mass energies around 91 GeV using an integrated luminosity of 4.7 pb-1. The aggreement with QED prediction is good. Consequently there is no evidence for non-standard channels which would have the same experimental signature. The lower limits on the QED cuttoff parameters are Λ+ > 113 GeV and Λ- > 95 GeV. An upper limit on the effective coupling between a possible excited electron and the gamma is derived. At 95% confidence level the branching ratios for Z0 decay into π0γ, ηψ and γγγ are below 1.5 × 10-4, 2.8 × 10-4 and 1.4 × 10-4 respectively., 0, info:eu-repo/semantics/published

Abstract: We present a search for the third generation up type quark t and a possible fourth down type quark b' in hadronic Z0 decays observed in DELPHI at the LEP collider. For any scenario with a decay through the charged current or into a charged Higgs with a mass at least 6 GeV/c2 below the t and 3 GeVc2 below the b' mass, we set a lower limit for the t quark mass at 44.0 GeV/c2 and for the b' mass at 44.5 GeV/c2. For specific scenarios the mass limits are slightly higher, e.g. for charged current decays the limits are 44.5 and 45.0 GeV/c2 respectively, where all limits are given at a 95% confidence level. © 1990., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: Measurements are presented of the cross section ratios Rℓ = σℓ(e+e-→ℓ+ℓ -)/σhh(e+e-→hadrons) for ℓ = e, μ and τ using data taken from a scan around the Z0. The results are Re = (5.09±0.32±0.18)%, Rμ = (4.96±0.35±0.17)% and Rτ,=(4.72±0.38± 0.29)% where, for the ratio Re, the t-channel contribution has been subtracted. These results are consistent with the hypothesis of lepton universality and test this hypothesis at the energy scale s ∼ 8300 GeV2. The absolute cross sections σℓ(e+e-→ℓ +ℓ-) have also been measured. From the cross sections the leptonic partial widths Γe = (83.2±3.0±2.4) MeV, (ΓeΓμ) 1/2=(84.6±3.0±2.4) MeV and (ΓeΓτ) 1/2=(82.6±3.3±3.2) MeV have been extracted. Assuming lepton universality the ratio Γℓ/Γh=(4.89±0.20± 0.12) × 10-2 was obtained, together with Γℓ=(83.6±1.8±2.2) MeV. The number of light neutrino species is determined to be Nv=3.12±0.24±0.25. Al the data are consistent with the predictions of the standard model., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: We study the stability of skyrmions in anisotropic layered magnets and consider a possible creation of the skyrmions in lightly doped layered cuprates. The picture of thermally excited and induced by the doped quasi-localized holes skyrmions is used to describe magnetic properties and spin kinetics of underdoped cuprates. A consistency of the skyrmion approach and the phase separation phenomenon is discussed.

Abstract: Hyperchaotic behaviour, occurring in systems which have two or more global expansion exponents (Lyapunov exponents), has been found for some model calculations which simulate strong chaotic selt-spiking (high fractal dimensions D > 5) of the microwave absorption observed by nonlinear antiferromagnetic resonance. The transition from chaos to hyperchaos was studied by varying the intermode coupling or the pumping field. In both cases, the transition was of the ‘hidden quasi-periodic’ type. Coupling a fourth mode creates very ‘noisy’ chaos with three positive Lyapunov exponents similar to measurements in antiferromagnetic resonance. In addition, the fourth mode acts as an internal control which could enforce transients to lower dimensional chaos and to fixed points.

Abstract: This paper presents results on charged Higgs boson production, based on LEP data collected at √s = 172 GeV, that complement the previous DELPHI results obtained at centre of mass energies up to 161 GeV. The charged Higgs bosons are assumed to be pair produced and to decay either into a quark pair or into τVτ. The three different possible final states are included in the analysis. Data from ring imaging Cherenkov and microvertex detectors are used to identify the quarks as a cs pair. The number of candidates found is compatible with the background expected from standard processes. Combining the results of the present analysis with those of the previous analysis at lower energies, a new lower mass limit for the charged Higgs boson is set at 54.5 GeV/c2. © 1998 Elsevier Science B.V.

Abstract: Trilinear gauge boson couplings are measured using data taken by DELPHI at 161 GeV and 172 GeV, Values for WWV couplings (V = Z,gamma) are determined from a study of the reactions e(+)e(-) --> W+W- and e(+)e(-) --> We nu, using differential distributions from the WW final state in which one W decays hadronically and the other leptonically, and total cross,section data from other channels, Limits are also derived on neutral ZV gamma couplings from an analysis of the reaction e(+)e(-) --> gamma + invisible particles.

Abstract: The data collected by DELPHI in 1996 have been used to measure the average charged particle multiplicities and dispersions in $q\bar{q}$ events at centre-of-mass energies of $\sqrt{s}=161$~GeV and $\sqrt{s}=172$~GeV, and the average charge multiplicity in WW events at $\sqrt{s}=172$~GeV. The multiplicities in $q\bar{q}$ events are consistent with the evolution predicted by QCD. The dispersions in the multiplicity distributions are consistent with Koba-Nielsen-Olesen (KNO) scaling. The average multiplicity of charged particles in hadronic W decays has been measured for the first time; its value, $19.23 \pm 0.74 (stat+syst)$, is consistent with that expected for an $e^+e^-$ interaction at a centre-of-mass energy equal to the W mass. The charged particle multiplicity in W decays shows no evidence of effects of colour reconnection between partons from different W's at the present level of statistics.

Abstract: In an analysis of multihadronic events recorded at LEP by DELPHI in the years 1992 through 1994, charged hadrons are identified using the measurement of their energy loss and their Cherenkov angle. Rapidity correlations of \La-\La, proton-proton, and \La-proton pairs are compared. The agreement with the string and cluster fragmentation models is tested. For those pairs that frame a meson in terms of rapidity the compensation of strangeness is studied. For \La{}$\overline{\mathrm{p}}$ pairs the additional correlation with respect to charged kaons is analysed.

Abstract: An upper limit for BR(Z(0) --> 3g) is obtained from a correlation method, which distinguishes statistically between quark and gluon jets by using the difference in their charged particle multiplicity distributions. From the sample of threefold symmetric three-jet events collected by the DELPHI experiment at LEP during 1991-1994, the 95% confidence level upper limit is deduced to be: BR(Z(0) --> 3g) less than or equal to 1.6 x 10(-2) for the JADE and BR(Z(0) --> 3g) less than or equal to 1.5 x 10(-2) for the DURHAM jet-finder.

Abstract: The hadronic photon structure function F_{2}^{gamma} has been measured in the Q^{2} range from 4 to 30~GeV^2/c^{4} and down to x values of order 0.001, using data taken with the DELPHI detector at LEP between 1991 and 1993. A comparison is made with several F_{2}^{gamma} parameterizations with special emphasis on their low x behaviour. A result on the Q^{2} evolution of F_{2}^{gamma} is presented.

Abstract: The average lifetime of b-baryons has been studied using 3 \times 10^6 hadronic Z^0 decays collected by the DELPHI detector at LEP. Three methods have been used, based on the measurement of different observables: the proper decay time distribution of 206 vertices reconstructed with a \Lambda, a lepton and an oppositely charged pion; the impact parameter distribution of 441 muons with high transverse momentum accompanied by a \mLs in the same jet; and the proper decay time distribution of 125 \Lambda_c-lepton decay vertices with the \Lambda_c exclusively reconstructed through its pK\pi, pK^0 and \mLs3\pi decay modes. The combined result is~:\par \begin{center} \tau(b-baryon) = (1.25^{+0.13}_{-0.11}\ pm0.04(syst)^{+0.03}_{-0. 05}(syst)) ps\par \end{center} where the first systematic error is due to experimental uncertainties and the second to the uncertainties in the modelling of the b-baryon production and semi-leptonic decay. Including the measurement recently published by DELPHI based on a sample of proton-muon vertices, the average b-baryon lifetime is ~:\par \begin{center} \tau(b-baryon) = (1.25\pm0.11(stat)\pm0.05(syst)) ps.\par \end{center}

Abstract: The interference between initial and final state radiation in the process \eemm\ at $\sqs \approx \MZ$ has been studied by measuring the forward-backward asymmetry as a function of the acoplanarity angle between the final state muons. The interference is expected to be sensitive to the space-time separation of the initial and final state radiation. The measured asymmetry distribution has been compared to theoretical predictions using the \KORALZ\ generator, with and without Ördalph\ interference. The magnitude of the interference between initial and $ \pm 0.06 $ (syst.) \GeV} . \end{center} has been extracted. The interpretation of this result is discussed. There is an additional uncertainty in the estimate of \GZ\ from as yet uncalculated higher order interference terms. By assuming a value of \GZ\ consistent with the world average, the data were used to estimate the size of these uncalculated corrections. The interference between initial and final state radiation in the process \eemm\ at \sqs \approx \MZ has been studied by measuring the forward-backward asymmetry as a function of the acoplanarity angle between the final state muons. The interference is expected to be sensitive to the space-time separation of the initial and final state radiation. The measured asymmetry distribution has been compared to theoretical predictions using the \KORALZ\ generator, with and without \ordalph\ interference. The magnitude of the interference between initial and final state radiation was found to be of the order predicted and to follow the expected distribution. Using the theoretical predictions, a value of \begin{center} \mbox{ \GZ = 2.50 \pm 0.21 (stat.) \pm 0.06 (syst.) \GeV} . \end{center} has been extracted. The interpretation of this result is discussed. There is an additional uncertainty in the estimate of \GZ\ from as yet uncalculated higher order interference terms. By assuming a value of \GZ\ consistent with the world average, the data were used to estimate the size of these uncalculated corrections.

Abstract: The tau lepton lifetime has been measured using three different methods with the DELPHI detector. Two measurements of one-prong decays are combined, accounting for correlations, giving a result of \tau_\tau = 291.8 \pm 3.3 \mbox{ (stat.)} \pm 2.0 \mbox{(sys.) fs} while the decay length distribution of three-prong decays gives the result \tau_{\tau} = 286.7 \pm 4.9 \mbox{ (stat.)} \pm 3.3 \mbox{ (sys.) fs}. Combining the results presented here with previous DELPHI measurements, we get \tau_{\tau} = 291.4 \pm 3.0 fs and find that the ratio of the coupling constant for tau decay relative to that for muon decay is 0.990 \pm 0.009, compatible with lepton universality.

Abstract: This analysis, based on a sample of 170000 hadronic Z0 decays, provides a measurement of the K± and p/View the MathML source differential cross sections which is compared to string- and cluster fragmentation models. The total multiplicities for K± and p/View the MathML source per hadronic event were found to be: NK = 2.26 ± 0.18 and Np = 1.07 ± 0.14. The positions ξ* of the maxima of the differential cross sections as a function of ξ = ln(1/xp) for K± and p/View the MathML source were determined to be 2.63 ± 0.07 and 2.96 ± 0.16 respectively. A comparison of the ξ* values for various identified particles measured at LEP with the prediction of the Modified Leading Logarithm Approximation with Local Parton Hadron Duality model has been performed. The measured ξ* position as a function of the hadron mass, after corrections due to particle decays, is in agreement with the model calculation.

Abstract: Two measurements of {Mathematical expression} are presented. Both measurements use 250000 Z decays taken with the DELPHI detector in 1991 and rely mainly on the precision of the microvertex detector. One tagging method is as simple as possible so that background rates can be reliably predicted by simulation. The other one uses a more involved tagging technique and reduces the dependence on simulation as much as possible. Combining both results, {Mathematical expression} is found to be 0.2209±0.0041(stat.)±0.0042(syst.)±0.0018 {Mathematical expression}. © 1995 Springer-Verlag.

Abstract: The partial decay width of theZ to $$b\bar b$$ quark pairs has been measured by the DELPHI detector at LEP.b-hadrons, containingb-quarks, were tagged by leptons with high transverse momentum relative to the hadron or by tracks with large impact parameters to the primary vertex. The ratio of the numbers of events with a single such tag to those with two tags was used to estimate the efficiency of the method and to reduce the systematic uncertainty. Combining all methods, the value: $$\begin{gathered} \frac{{\Gamma _{b\bar b} }}{{\Gamma _{had} }} = 0.2210 \pm 0.0033 \pm 0.0003(model) \hfill \\ \pm 0.0014(\Gamma _{c\bar c} ) \hfill \\ \end{gathered} $$ was found, where the third error corresponds to a±8% uncertainty on the $$c\bar c$$ production width. A maximum likelihood in to the single and di-lepton distributions gave the branching fraction of the decays ofb-quarks to leptons as: $$\begin{gathered} BR(b \to l) = (11.06 \pm 0.39 \pm 0.19(model) \hfill \\ \pm 0.12(\Gamma _{c\bar c} ))\% . \hfill \\ \end{gathered} $$

Abstract: A search for pair production of neutral heavy Higgs bosons decaying into bb has been carried out in a study of hadronic decays of the Z boson into four jet final states using data taken by DELPHI in 1991 and 1992. The two production mechanisms present in the two Higgs doublets scheme, bremsstrahlung production of hZ* and associated production of hA, may lead to four beauty jets well recognizable using the precise microvertex detector measurements. No evidence for a signal was found, leading to limits on BR(ZrarrhArarr4b) from 3.5 to 5.5×10–4 at 95% contidence level, depending on the mass of the ligthest Higgs. When combined with the results of the recent DELPHI standard Higgs search, this result allows the kinematical limit to be reached for the masses of h and A in the minimal supersymmetric extension of the Standard Model (MSSM) scheme. It also allows the tanbetale1 domain to be explored, and a region above the kinematic limit for direct hA production is constrained by considering virtual hA production. Results are also given in the general two-doublet scheme.

Abstract: A sample of 25000 Z(0) --> tau(-)tau(+) events collected by the DELPHI experiment at LEP in 1991 and 1992 is used to measure the leptonic branching fractions of the tau lepton. The results are B(tau --> e nu) = (17.51+/-0.39)% and B(tau --> mu nu) = (17.02+/-0.31)%. The ratio of the muon and electron couplings to the weak charged current is measured to be g(mu)/g(e) = 1.000+/-0.013, satisfying e-mu universality. The average leptonic branching fraction corrected to the value for a massless lepton, assuming e-mu universality, is found to be B(tau --> l nu) = (17.50+/-0.25)%.

Abstract: K0SK0S correlations have been studied in a sample of 717 511 hadronic events collected by the DELPHI detector at LEP during 1992. An enhancement is found in the production of pairs of K0S of similar momenta, as compared with a Monte Carlo simulated reference sample. The measured values for the strength of the correlation and the radius of the emitting source of kaons are λ = 1.13 ± 0.54 (stat) ± 0.23 (syst) and r = 0.90 ± 0.19 (stat) ± 0.10 (syst) fm. This enhancement is consistent with the hypothesis that K0SK0S pairs display an enhancement, regardless of whether they come from a K0K0 or from a K0K0 (K0K0) system.

Abstract: Kaon production in one prong tau decays has been studied using data collected with the DELPHI detector at the LEP collider Charged kaons were identified over a large momentum range by the DELPHI barrel Ring Imaging Cherenkov detector. The following branching ratios have been determined: BR(τ → Kντ) = (0.85 ± 0.18) %, BR(τ → Kντ ≥ 0 neutrals) = (1.54 ± 0.24)%, BR(τ → Kντ ≥ 1 neutrals) = (0.69 ± 0.25)%. The result for the exclusive branching ratio is consistent with the Standard Model prediction based on τ - μ - e universality. In addition, tau decay into K*- was studied in the channel K*- → K-π0. The result BR(τ → K*-ντ) x BR(K*- → K-w0) = (0.57 ± 0.23)% was obtained.

Abstract: The time dependent mixing of View the MathML source mesons has been observed by using the correlations between the charge of D∗ mesons and the weighted mean charge of particles in each hemisphere. From a reconstructed D∗± sample corresponding to about 1.7 million hadronic Z0 decays, the mass difference between the two Bd0 mass eigenstates has been measured to be View the MathML source or, converting into eV/c2: Δm = [3.29 ± 0.79 (stat) ± 0.39 (syst.)] 10−4 eV/c2.

Abstract: J/psi mesons have been reconstructed from their decay to mu(+)mu(-) and e(+)e(-), using the data collected by the DELPHI experiment during 1991 and 1992 at the LEP collider. From about 1 million hadronic Z decays 153 +/- 17 J/psi were found, 5.4 +/- 2.3 psi' were obtained in the channel J/psi(--> mu(+)mu(-))pi(+)pi(-) and 6.4 +/- 2.7 chi(c) in the channel J/psi(--> mu(+)mu(-))gamma. As the dominant source of J/psi mesons is from b quarks, the following branching ratios: Br(b-->J/psi X) = (1.12 +/- 0.12 (stat.) +/- 0.10 (syst.))%, Br(b --> psi' X) = (0.48 +/- 0.22 (stat.) +/- 0.10 (syst.))%, Br(b-->chi(cl) X) = (1.4 +/- 0.6 (stat.)(-0.2)(+0.4) (syst.))% were measured. From the proper time distribution of the J/psi sample, the average lifetime of b-hadrons decaying into J/psi was found to be: tau(B) = 1.50(-0.21)(+0.24) (stat.) +/- 0.03 (syst.) ps. A search for completely reconstructed B meson decays to final states including a J/psi gave a signal of 15 +/- 5 events.

Abstract: The tau lepton lifetime is measured using four different methods with the DELPHI detector. Three measurements using one prong decays are combined, accounting for correlations, resulting in tau(tau) = 298 +/- 7 (stat.) +/- 4 (syst.) fs while the decay length distribution of three prong decays gives tau(tau) = 298 +/- 13 (stat.) +/- 5 (syst.) fs. The combined result is tau(tau) = 298 +/- 7 fs. The ratio of the Fermi coupling constant from tau decay relative to that from muon decay is found to be 0.985 +/- 0.013, compatible with lepton universality.

Abstract: Distributions of event shape variables obtained from 120600 hadronic Z decays measured with the DELPHI detector are compared to the predictions of QCD based event generators. Values of the strong coupling constant αs are derived as a function of the renormalization scale from a quantitative analysis of eight hadronic distributions. The final result, αs(MZ), is based on second order perturbation theory and uses two hadronization corrections, one computed with a parton shower model and the other with a QCD matrix element model. © 1992 Springer-Verlag.
