Abstract: Time-dependent ${{\rm B^{0}}\mbox{-}\bar{{\rm B}}^{0}}$ mixing is studied using about two million hadronic Z decays registered by L3 in 1994 and 1995. For this study three techniques are used. Tagging of the b-quark charge at decay time is performed by identifying leptons from semileptonic B decays. The flavour of the b quark at production time is determined from the charge of the lepton in the opposite hemisphere or by using a jet-charge technique. The proper time of the B-particle decay is obtained by reconstructing the production and decay vertices or by a measurement of the lepton impact parameter. The combined result for the frequency of ${{\rm B_d^0}}$ meson oscillations is

Abstract: We have studied the process $e^+e^-{\rightarrow}\rm n {\gamma}$ $(\rm n{\ge}2)$ at centre-of-mass energies of 161.3 GeV and 172.1 GeV. The analysis is based on a sample of events collected by the L3 detector in 1996 corresponding to total integrated luminosities of 10.7 ${\rm pb^{-1}}$ and 10.1 ${\rm pb^{-1}}$ respectively. The observed rates of events with two and more photons and the characteristic distributions are in good agreement with the Standard Model expectations. This is used to set lower limits on contact interaction energy scale parameters, on the QED cut-off parameters and on the mass of excited electrons.

Abstract: A search for unstable neutral and charged heavy leptons as well as for stable charged heavy leptons has been made at center-of-mass energies s = 161 GeV and s 172 GeV with the L3 detector at LEP. No evidence for their existence was found. We exclude unstable neutral leptons of Dirac (Majorana) type for masses below 78.0 (66.7), 78.0 (66.7) and 72.2 (58.2) GeV, if the heavy neutrino couples to the electron, muon or tau family, respectively. We exclude unstable charged heavy leptons for masses below 81.0 GeV for a wide mass range of the associated neutral heavy lepton. The production of stable charged heavy leptons with a mass less than 84.2 GeV is also excluded. If the unstable charged heavy lepton decays via mixing into a massless neutrino, we exclude masses below 78.7 GeV.

Abstract: We report on measurements of $\mathrm{e^+e^-}$ annihilation into hadrons and lepton pairs. The data have been taken with the L3 detector at LEP at centre--of--mass energies between 161~$\mathrm{Ge\kern -0.12em V}$ and 172~$\mathrm{Ge\kern -0.12em V}$. In a data sample corresponding to 21.2~pb$^{-1}$ of integrated luminosity 2728 hadronic and 868 lepton--pair events are selected. The measured cross sections and leptonic forward--backward asymmetries agree well with the Standard Model predictions. \end{abstract}

Abstract: We present a study of the structure of hadronic events recorded by the L3 detector at LEP at the center of mass energies of 161 and 172 GeV. The data sample corresponds to an integrated luminosity of 21.25 pb-1 collected during the high energy runs of 1996. The distributions of event shape variables and the energy dependence of their mean values are well reproduced by QCD models. From a comparison of the data with resummed second order QCD calculations, we determine the strong coupling constant at the two energies. Combining with our earlier measurements we find that the strong coupling constant decreases with increasing energy as expected in QCD.

Abstract: A search for excited leptons $\rm e^*,~\mu^*, ~\tau^*$ and $\nu_{\rm e}^*$ in $\rm e^+e^-$ collisions at $\rm \sqrt{s}$ = 161 GeV is performed using the $\rm 10.8 ~pb^{-1}$ of data collected by the L3 detector at LEP. No evidence has been found for their existence. From an analysis of the expected $\ell^*\ell^*$ pair production in the channels $\rm ee\gamma\gamma$, $\rm \mu\mu\gamma\gamma$, $\rm \tau\tau\gamma\gamma$, $\rm eeWW$, and $\rm \nu\nu\gamma\gamma$, the lower mass limits at 95\% C.L. are 79.7 GeV for $\rm e^{*}$, 79.9 GeV for $\mu^{*}$, 79.3 GeV for $\tau^{*}$ and 71.3 GeV for $\nu_{\rm e}^{*}$ assuming the same couplings as for standard leptons. From an analysis of the expected $\ell\ell^*$ single production in channels $\rm ee\gamma$, $\mu\mu\gamma$, $ \tau\tau\gamma$, $\rm \nu_{e}eW$ and $\nu\nu\gamma$, the upper limits on the couplings $\lambda/m_{\ell^*}$ up to $m_{\ell^{*}}$ = 161 GeV are determined.

Abstract: Using a data sample of 1 475 000 Z → qq(γ) events collected during 1994 with the L3 detector at LEP, we have studied the purely leptonic decays of heavy flavour mesons, D s − → τ − ν τ and B − → τ − ν τ . A signal is observed in the invariant mass distribution M(γD s − ) corresponding to the decay sequence D ∗− → γD s − , D s − → τ − ν τ , τ − → l − ν l ν τ . The branching fraction for D s − → τ − ν τ decays is measured to be β (D s − → τ − ν τ ) = 0.074 ± 0.028(stat) ± 0.016(syst) ± 0.018(norm) . No signal of B − → τ − ν τ decays is observed in the data, corresponding to an upper limit on the branching franction β( B − → τ − ν τ ) −4 at 90% CL.

Abstract: We have searched for evidence of Upsilon production in 3.5 million hadronic Z decays collected by the L3 detector at LEP in 1991-1995. No signals are observed for the decay chain Z -> Upsilon X; Upsilon -> l+l- (l= e, mu), therefore upper limits at the 95% confidence level are set on the following Z branching fractions: BR (Z -> Upsilon(1S) X) < 5.5 x 10**-5; BR (Z -> Upsilon(2S) X) < 13.9 x 10**-5; BR (Z -> Upsilon(3S) X) < 9.4 x 10**-5.

10. The effect of pion condensation on superfluidity in neutron stars

Abstract: The authors study the effect of pion condensation on the energy gap of superfluid neutron matter. The neutron energy spectrum is determined in a Walecka-type model in the mean-field approximation. This spectrum is inserted into the BCS model to calculate the energy gap for singlet pairing superfluid neutron matter. With this procedure they calculate the energy gap for pion condensed and normal matter at various densities. It turns out that in the superfluid density region the pion condensation is too weak to modify the energy gap significantly.

Abstract: Using the data collected with the L3 detector at LEP between 1990 and 1995, corresponding to an integrated luminosity of 149 pb−1, the τ longitudinal polarisation has been measured as a function of the production polar angle using the τ decays τ−→h−ντ (h=π,ρ,a1) and τ−→ℓ−ν̄ℓντ (ℓ=e,μ). From this measurement the quantities Ae and Aτ, which depend on the couplings of the electron and the τ to the Z, are determined to be Ae=0.1678±0.0127±0.0030 and Aτ=01540±0.0088±0.0062, consistent with the hypothesis of e–τ universality. Under this assumption a value of Aℓ=0.1540±0.0074±0.0044 is obtained, yielding the value of the effective weak mixing angle sin2θW=0.2306±0.0011. Facultad de Ciencias Exactas

Abstract: Local multiplicity fluctuations in hadronic Z decays are studied using the L3 detector at LEP. Bunching parameters are used for the first time in addition to the normalised factorial moment method. The bunching parameters directly demonstrate that the fluctuations in rapidity are multifractal. Monte Carlo models show agreement with the data, reproducing the trend, although not always the magnitude, of the factorial moments and bunching parameters., Facultad de Ciencias Exactas

Abstract: A study of neutral-current four-fermion processes is performed, using data collected by the L3 detector at LEP during high-energy runs at centre-of-mass energies 130 - 136, 161 and 170 - 172 GeV, with integrated luminosities of 4.9, 10.7 and 10.1 pb$^{-1}$, respectively. The total cross sections for the final states $ \ell\ell \ell^\prime \ell^\prime $ and $\rm \ell\ell qq $ ($\ell$,~$\ell^\prime $ = e, $\mu$ or $\tau$) are measured and found to be in agreement with the Standard Model prediction.

Abstract: We report on measurements of mass and total decay width of the W boson and of triple-gauge-boson couplings, γWW and ZWW, with the L3 detector at LEP. W-pair events produced in e+e− interactions between 161 GeV and 172GeV centre-of-mass energy are selected in a data sample corresponding to a total luminosity of 21.2 pb−1. The mass and total decay width of the W boson are determined to be MW = 80.75−0.27+0.26(exp.) ± 0.03 (LEP) GeV and ΓW = 1.74−0.78+0.88(stat.) ± 0.25(syst.)GeV, respectively. Limits on anomalous triple-gauge-boson couplings, γWW and ZWW, are determined, in particular −1.5 < δZ < 1.9 (95% CL), excluding vanishing ZWW coupling at more than 95% confidence level., Facultad de Ciencias Exactas

Abstract: A search for the Standard Model Higgs boson has been performed with the L3 detector at LEP. The data sample was collected at three centre-of-mass energies, 161.3, 170.3 and 172.3 GeV with integrated luminosities of 10.8, 1.0 and 9.2 pb, respectively. No Higgs signal is observed. In combination with previous data taken at the Z resonance, a lower Higgs mass limit, MH > 69.5 GeV, is obtained at 95% confidence level., Facultad de Ciencias Exactas

Abstract: We have studied the structure of hadronic events with a hard, isolated photon in the final state (e+e− → Z → hadrons + γ) in the 3.6 million hadronic events collected with the L3 detector at centre-of-mass energies around 91 GeV. The centre-of-mass energy of the hadronic system is in the range 30 GeV to 86 GeV. Event shape variables have been measured at these reduced centre-of-mass energies and have been compared with the predictions of different QCD Monte Carlo programs. The event shape variables and the energy dependence of their mean values are well reproduced by QCD models. We fit distributions of several global event shape variables to resummed O(αs2) calculations to determine the strong coupling constant αs over a wide range of energies. We find that the strong coupling constant αs decreases with increasing energy, as expected from QCD., Facultad de Ciencias Exactas

Abstract: We report on the measurement of W-boson pair-production with the L3 detector at LEP at an average centre-of-mass energy of 172.13 GeV. In a data sample corresponding to a total luminosity of 10.25 pb−1 we select 110 four-fermion events with pairs of hadronic jets or leptons with high invariant masses. Branching fractions of W decays into different fermion-antifermion pairs are determined with and without the assumption of charged-current lepton universality. The branching fraction for hadronic W decays is measured to be: B(W → hadrons) = 64.2+3.7−3.8 (stat.) ± 0.5 (syst.) %. Combining all final states the total cross section for W-pair production is measured to be: σWW = 12.27+1.41−1.32 (stat.) ± 0.23 (syst.) pb. The results are in good agreement with the Standard Model., Facultad de Ciencias Exactas

Abstract: A study of resonance formation is presented in the π+ π- π0 final state in two-photon collisions at LEP. The a2(1320) radiative width is measured to be Γγγ = 0.98 ± 0.05 ± 0.09 keV. The helicity 2 production is dominant. Exclusive π+ π- π0 production has also been studied in the mass region above the a2 in the pπ and f2π channels.

Abstract: The two-photon collision reaction e+e- → e+e- l+l- has been studied at √s ≈ 91 GeV using the L3 detector at LEP for l = e, μ, τ. We have analysed untagged configurations where the two photons are quasi-real. Good agreement is found between our measurements and the O(α4) QED expectation., Facultad de Ciencias Exactas

Abstract: We report on the measurement of W-boson pair-production with the L3 detector at LEP at a centre-of-mass energy of 161.34 GeV. In a data sample corresponding to a total luminosity of 11 pb−1, we select four-fermion events with high invariant masses of pairs of hadronic jets or leptons. Combining all final states, the measured total cross section for W-pair production is: sigmaWW = 2.89+0.81-0.42(stat.) ± 0.14 (syst.) pb. Within the Standard Model, this corresponds to a mass of the W boson of: MW = 80.80+0.48-0.42 (exp.) ± 0.03 (LEP) GeV. Limits on anomalous triple-vector-boson couplings are derived., Facultad de Ciencias Exactas

Abstract: A search for the Standard Model Higgs boson has been performed with the L3 detector at LEP. The data sample was collected at three centre-of-mass energies, 161.3, 170.3 and 172.3 GeV with integrated luminosities of 10.8, 1.0 and 9.2 pb, respectively. No Higgs signal is observed. In combination with previous data taken at the Z resonance, a lower Higgs mass limit, M-H > 69.5 GeV, is obtained at 95% confidence level. (C) 1997 Elsevier Science B.V.

Abstract: We report on the measurement of W-boson pair-production with the L3 detector at LEP at a centre-of-mass energy of 161.34 GeV. In a data sample corresponding to a total luminosity of II pb(-1), we select four-fermion events with high invariant masses of pairs of hadronic jets or leptons. Combining all final states, the measured total cross section for W-pair production is: sigma(ww) = 2.89(-0.70)(+0.81) (stat.) +/- 0.14 (syst.) pb. Within the Standard Model, this corresponds to a mass of the W boson of M-w = 80.80(-0.42)(+0.48) (exp.) +/- 0.03 (LEP) GeV. Limits on anomalous triple-vector-boson couplings are derived.

Abstract: We investigate the possibility that the difference between the measurements of $\alpha_3(M_Z)$ from the hadronic branching ratio of the $Z^0$ and the world average of other measurements is due to the decay of the $Z^0$ into quark, anti-squark, and gluino. Consequences for supersymmetry breaking models are discussed., Comment: 9 pages, 4 figures not included

Abstract: The silicon nitride ceramics are usually known as strongly refractory and enduring materials and have typical electrically insulating properties. If the reinforcing phase of ceramic composite (that is mainly put in the material to improve mechanical properties) is a good electrical conductor, it is worth to investigate the composite in electrical aspect. In this work carbon nanotubes, black-carbon and graphite were added to the basic silicon nitride ceramic and the electrical conductivity of the prepared carbon-ceramic composites was determined. The conductivity of the ceramic composites with different type and concentration of the carbon additives was observed by applying four point DC resistance measurements. Insulator and conductor composites in a wide conductivity range can be produced depending on the type and quantity of the additives. The additive types as well as the sintering parameters have influence on the basic electrical properties of the conductor composites.

Abstract: Using the data collected by the L3 experiment at LEP from 1991 to 1995 at energies around the Z mass, a measurement of the weak anomalous magnetic dipole moment, awτ, and of the weak electric dipole moment, dwτ, of the τ lepton is performed. These quantities are obtained from angular distributions in e+e−→τ+τ−→h+ν̄τh−ντ, where h is a π or a p. The results are: Re(awτ)=(0.0±1.6±2.3)×10−3, Im(awτ)=(−1.0±3.6±4.3)×10−3 and Re(dwτ)=(−0.44±0.88±1.33)×10−17e·cm. This is the first direct measurement of awτ., Facultad de Ciencias Exactas

Abstract: Local multiplicity fluctuations in angular phase space intervals are studied using factorial moments measured in hadronic events at √s≃91.2 GeV, which were collected by the L3 detector at LEP. Parton shower Monte Carlo programs agree well with the data. On the other hand, first-order QCD calculations in the Double Leading Log Approximation and the Modified Leading Log Approximation are found to deviate significantly from the data., Facultad de Ciencias Exactas

Abstract: We present a measurement of the average b-hadron lifetime t at the eqey collider LEP. Using hadronic Z decays b collected in the period from 1991 to 1994, two independent analyses have been performed. In the first one, the b-decay position is reconstructed as a secondary vertex of hadronic b-decay particles. The second analysis is an updated measurement of t using the impact parameter of leptons with high momentum and high transverse momentum. The combined result is τb=[1549±9(stat)±15(syst)]fs. In addition, we measure the average charged b-decay multiplicity 〈nb〉and the normalized average b-energy 〈xE〉b at LEP to be 〈nb〉=4.90±0.04(stat)±0.11(syst),〈xE〉b=0.709±0.004(stat+syst)., Facultad de Ciencias Exactas

Abstract: Charged and neutral particle multiplicities of jets associated with identified semileptonic and hadronic b decays are studied. The observed differences between these jets are used to determine the inclusive properties of the weak charged hadronic current. The average charged particle multiplicity of the weak charged hadronic current in b decays is measured for the first time to be 2.69$\pm$0.07(stat.)$\pm$0.14(syst.). This result is in good agreement with the JETSET hadronization model of the weak charged hadronic current if 40$\pm$17\% of the produced mesons are light--flavored tensor (L=1) mesons. This level of tensor meson production is consistent with the measurement of the $\pi^0$ multiplicity in the weak charged hadronic current in b decays. \end{abstract}
