Abstract: A search for rare charmless decays of B0d and B0s mesons has been performed in the exclusive channels B0d(s) →ηη0, B0d(s) →ηπ0 and B0d(s) →π0π0. The data sample consisted of three million hadronic Z decays collected by the L3 experiment at LEP from 1991 through 1994. No candidate event has been observed and the following upper limits at 90% confidence level on the branching ratios have been set: Br(B0d→ηη) −4, Br(B0s →ηη) < 1.5 x 10−3, Br(B0d→ηπ0) < 2.5 x 10−4, Br(B0s→ηπ0) < 1.0 x 10−3, Br(B0d→π0π0) < 6.0 x 10−5, Br(B0s→π0π0) < 2.1 x 10−4. These are the first experimental limits on Bd0→ηη and on the Bs0 neutral charmless modes., Facultad de Ciencias Exactas

Abstract: The inclusive semileptonic branching ratios b→eνX,μ νX,τ νX andνX have been measured at LEP with the L3 detector. The analysis is based on 2-jet hadronic Z decays obtained in the data collected between 1991 and 1992. Three separate event samples are analysed, containing electrons, muons and large missing energy (neutrinos), respectively. From the electron sample, we measure Br(b→eνX)=(10.89±0.20±0.51)% and, from the muon sample, Br(b→μ νX)=(10.82±0.15±0.59)%, where the first error is statistical and the second is systematic. From the missing energy sample, we measure Br(b→νX)=(23.08±0.77±1.24)%, assuming the relative semileptonic decay rates e:μ:τ=1:1:(0.25±0.05), according to theoretical expectations. From a combined analysis of all three samples and constraining the relative semileptonic rates, we measure Br(b→eνX)=Br(b→μ νX)=(10.68±0.11±0.46)%. Alternatively, we can remove the constraint on the relative semileptonic rates and measure Br(b→τ νX)=(1.7±0.5±1.1)%.

Abstract: The reaction \epem\ra\epem\gamma^*\gamma^*\ra\epem\kos\kos is studied with the L3 detector at LEP and the formation of the f_2\, \!\!\!'(1525) resonance is observed. For an integrated luminosity of 114 \pb, % \ collected over the years 1991-1994, 31\pm6 f_2\, \!\!\!' events are found. Their angular distribution is consistent with a pure helicity two. The radiative width times the branching ratio is measured to be \Gamma_{\gamma\gamma}(f_2\,\!\!\!')\times Br(f_2\ \!\!\!'\ra \k\bar{\k})=(0.093\pm 0.018\pm 0.022) keV. Only three events are found in the f_2(1270)-a_2(1320) mass region, consistent with destructive f_2-a_2 interference in the \kos\kos \ final state. The mixing angle of the tensor meson nonet is determined to be \theta=(29.4^{+1.4}_{-1.6})^\circ.

Abstract: A search for the decays B d,s 0 → γγ in 2.95 million hadronic Z decays has been performed using the L3 detector at LEP. No candidates are found in the signal region and upper limits have been set on the branching ratios: Br(B d 0 → γ ) −5 and Br(B s 0 → γγ ) −5 at 90% CL. These are the first limits set on these exclusive rare decays.

Abstract: Total and differential cross sections for the process e+e− → γγ(γ), and the total cross section for the process e+e− → γγγ, are measured at energies around 91 GeV using the data collected with the L3 detector from 1991 to 1993. We set lower limits, at 95% CL, on a contact interaction energy scale parameter Λ > 602 GeV, on the mass of an excited electron and on the QED cut-off parameters Λ+ > 149 GeV and Λ_ > 143 GeV. Upper limits are also set o branching fractions of Z decaying into γγ, π° and ηγ of 5.2 × 10−5, 5.2 × 10−5 and 7.6 × 10−5 respectively. The reactions e+e− → ℓ+ℓ−nγ (ℓ = e, μ, τ) are studied using the data collected from 1990 to 1994. The data are consistent with the QED expectations., Facultad de Ciencias Exactas

Abstract: We have measured the time integrated B0 B 0 mixing parameter and the forward-backward asymmetry in the process e+e− → b b using hadronic events containing muons or electrons. The data sample corresponds to 1,044,000 hadronic decays of the Z. From a fit to the momentum and transverse momentum distributions for single lepton and dilepton events, we have determined the B0 B 0 mixing parameter to be χB = 0.123 ± 0.012 (stat.) ± 0.008 (sys.), and the b b forward-backward asymmetry at the effective center-of-mass energy √s = 91.30 GeV to be A b b = 0.087 ± 0.011 ( stat. ) ± 0.004 ( sys. ) This measurement corresponds to a value of the effective electroweak mixing angle of sin 2 θ w = 0.2335 ± 0.0021 .

Abstract: Spin precession of channeled particles in bent crystals has been observed for the first time. Polarized SIGMA+ were channeled using bent Si crystals. These crystals provided an effective magnetic field of 45 T which resulted in a measured spin precession of 60-degrees +/- 17-degrees. This agrees with the prediction of 62-degrees +/- 2-degrees using the world average of SIGMA+ magnetic moment measurements. This new technique gives a SIGMA+ magnetic moment of (2.40 +/- 0.46 +/- 0.40),mu(N), where the quoted uncertainties are statistical and systematic, respectively. We see no evidence of depolarization in the channeling process.

Abstract: We present a study of the inclusive production of neutral pions and charged particles from 112 000 hadronic Z 0 decays. The measured inclusive momentum distributions can be reproduced by parton shower Monte Carlo programs and also by an analytical QCD calculation. Comparing our results to e + e − data between √ s = 9 and 91 GeV, we findfind that the evolution of the spectra with center of mass energy is consistent with the QCD predictions.

Abstract: From 2540 Z0 → τ+τ− events, we determine the inclusive decay branching fractions of the τ-lepton into one and three charged particles to be 0.856 ± 0.006 (stat.) ± 0.003 (syst.) and 0.144 ± 0.006 (stat.) ± 0.003 (syst.), respectively. The leptonic branching fractions are measured to be 0.175 ± 0.008 (stat.) ± 0.005 (syst.) for τ → μνμντ and 0.177 ± 0.007 (stat.) ± 0.006 (syst.) for τ → eνeντ. We determined the τ lifetime both from three-prong decays using the decay length and from one-prong decays using the impact parameter. The results from the two independent methods agree and yield a combined value of [0.309 ± 0.023 (stat.) ± 0.030 (syst.)] × 10−12s.

Abstract: We have measured the forward-backward asymmetry in Z 0 → b b decays using hadronic events containing muons and electrons. The data sample corresponds to 118 200 hadronic events at √s≈Mz. From a fit to the single and dilepton p and P⊥ spectra, we determine A b b =0.130 −0.042 +0.044 including the correction for B 0 − B 0 mixing.

Abstract: Whatever the field, major change implies as much as deep transformation of thinking i.e to put in network new skills in particular, those made available by the availability of new technologies. In this context, only one individual cannot join together all necessary skills. It becomes clear that the goal of space valorization cannot be considered without relational investment between the partners and their accumulated background. The local empowerment concerns a collective phenomenon of acquisition and development of skills rests on an learning way appropriate to the potential of the territory to form or promote. The local mediation sets for objective the creation of relations between pre-existent skills and their transfer between the actors, individuals or groups, private or public. But the capacity of the territory to solve these problems will depend closely on the richness of the network and co-operations which it shelters or it will suggest.

Abstract: We have searched for charged and neutral leptons. We exclude stable Dirac neutrinos below 42.8 GeV and stable Majorana neutrinos below 34.8 GeV. From a search for unstable neutrinos we exclude masses below 46.4 GeV (Dirac) and below 45.1 GeV (Majorana). We exclude all masses of sequential charged and neutral leptons, except if both masses are larger than 42.8 GeV (for stable Dirac neutrinos). All mass limits correspond to 95% CL.

Abstract: We have measured the partial widths of the Z 0 into lepton pairs, and the forward-backward charge asymmetry for the process e + e − → μ + μ − using the L3 detector at LEP. We obtain an average Γ ll of 83.0±2.1±1.1 MeV.From this result and the asymmetry measurement, we extract the values of the vector and axial vector couplings of the Z 0 to leptons: g rmv =−0.066 −0.027 +0.046 and g rmA = −0.495 −0.007 +0.007 .

Abstract: The aim of the MuCap experiment is a 1% measurement of the singlet capture rate Lambda_S for the basic electro-weak reaction mu + p -> n + nu_mu. This observable is sensitive to the weak form-factors of the nucleon, in particular to the induced pseudoscalar coupling constant g_P. It will provide a rigorous test of theoretical predictions based on the Standard Model and effective theories of QCD. The present method is based on high precision lifetime measurements of mu^- in hydrogen gas and the comparison with the free mu^+ lifetime. The mu^- experiment will be performed in ultra-clean, deuterium-depleted H_2 gas at 10 bar. Low density compared to liquid H_2 is chosen to avoid uncertainties due to ppmu formation. A time projection chamber acts as a pure hydrogen active target. It defines the muon stop position in 3-D and detects rare background reactions. Decay electrons are tracked in cylindrical wire-chambers and a scintillator array covering 75% of 4 pi., Int.

Abstract: The production of B∗ mesons in Z decays has been measured at LEP with the L3 detector. A sample of Z → b events was obtained by tagging muons in 1.6 million hadronic Z decays collected in 1991, 1992 and 1993. A signal with a peak value of Eγ = 46.3 ± 1.9 (stat) MeV in the B rest frame energy spectrum was interpreted to come from the decay B∗ → γB. The inclusive production ratio of B∗ mesons relative to B mesons was determined from a fit to the spectrum to be , where the first error is statistical and the second is systematic., Facultad de Ciencias Exactas

Abstract: Contains fulltext : 28371.pdf (Author’s version preprint ) (Open Access) The neutrino energy spectrum in semileptonic b-hadron decays with identified energetic electrons and muons has been measured. The observed relative energy sharing between the neutrino and the cahrged lepton is found to be well described with a W± polarization obtained from a free b-quark decay model with a (Vf-A)×(Vf-A) decay structure. The alternative of a (V+A)×(Vf-A) decay structure is excluded with a significance of more than 6 standard deviations. The possibility that hadronic corrections to the b-hadron decay destroy any W± polarization is disfavored by more than 3 standard deviations.

Abstract: We have searched for neutralinos produced via the reactions e+e− → χχ′ and e+e−→ χ′χ′, where the next-to lightest neutralino, χ′, decays into the lightest neutralino, χ, and either a photon or a fermion pair. Based on 1.8 × 106 hadronic Z decays collected with the L3 detector at LEP, no signal has been observed. We present upper limits of a few times 10−5 on the branching ratios Z → χχ′ and Z → χ′χ′. In the framework of the Minimial Supersymmetric Standard Model, we exclude a lightest χ with mχ less than 18 GeV, if either tan β > 2 or the gluino mass m≈g > 100 GeV., Facultad de Ciencias Exactas

Abstract: We present evidence for soft gluon interference, as required by QCD. This interference is expected to manifest itself in an angular ordering of the gluons radiated within a jet. Using hadronic decays of the Z boson in the L3 detector at LEP, we compare variables sensitive to such an angular ordering, namely the energy-energy correlation asymmetry and the newly introduced particle- particle correlation asymmetry, with the predictions of various parton shower models. Only those models which incorporate the expected interference agree with the data., Facultad de Ciencias Exactas

Abstract: We have analyzed one-prong τ decays with neutral kaons using the information from a fine-grained hadron calorimeter. The data sample consists of 43 500 Z → τ+τ−(γ) events collected by the L3 detector at LEP in 1991, 1992 and 1993. The following branching fractions are measured: B(τ− → ν-π Kº) = 0.0095 ± 0.0015 (stat) ± 0.0006(syst); B(τ− → vπºKº) = 0.0041 ± 0.0012(stat) ± 0.0003(syst) and B(τ− → vπ-K°Kº) = 0.0031 ± 0.0012(stat) ± 0.0004( syst)., Facultad de Ciencias Exactas

Abstract: We report on the measurement of the leptonic and hadronic cross sections and leptonic forward-backward asymmetries at theZ peak with the L3 detector at LEP. The total luminosity of 40.8 pb−1 collected in the years 1990, 1991 and 1992 corresponds to 1.09·106 hadronic and 0.98·105 leptonic Z decays observed. These data allow us to determine the electroweak parameters. From the cross sections we derive the properties of the Z boson: MZ=91195 ± 9 MeVΓZ=2494 ± 10 MeV Γhad=1748 ± 10 MeVΓℓ=83.49 ± 0.46MeV assuming lepton universality. We obtain an invisible width of Γinv=496.5 ± 7.9 MeV which, in the Standard Model, corresponds to a number of light neutrino species of Nv=2.981 ± 0.050. Using also the three leptonic forward-backward asymmetries and the average tau polarization, we determine the effective vector and axial-vector coupling constants of the neutral weak current to charged leptons to be: g¯ℓv=−0.0378+0.0045−0.0042 g¯ℓA=−0.4998 ± 0.0014. Within the framework of the Standard Model, and including our measurements of the Z→b¯b forward-backward asymmetry and partial decay width, we derive an effective electroweak mixing angle of sin2¯θW=0.2326 ± 0.0012 . We obtain an estimate for the strong coupling constant, αS=0.142 ± 0.013 and for the top-quark mass,mt =158+32−40 ± 19(Higgs) GeV, where the second error arises due to the uncertainty in the Higgs-boson mass., Facultad de Ciencias Exactas

Abstract: We search for new resonances, Y, with mass MY, in the range from 30 to 89 GeV, produced via the reaction e+e− → Z0 →γY, where Y subsequently decays into e+e−, μ+μ− or hadrons. We use 5.5.pb−1 of data collected in the energy range 88.2 ≤ √s ≤ 94.2 GeV, near the Z0 peak. We obtain the following upper limits, at the 95% confidence level, on the product of the branching ratios: BR(Z0 → γY) × BR(Y → e+e−) < 2.8 × 10−4 for 30 < MY < 89, BR(Z0 →γY × BR(Y → μ+μ−) < 2.3 × 10−4 for 30 < MY < 89, BR(Z0→ γY) × BR(Y → hadrons) < 4.7 × 10−4 for 30 < MY < 86. These limits are valid for resonances with widths smaller than our mass resolution., Facultad de Ciencias Exactas

Abstract: We have measured the decay properties of from a study of inclusive muon and electron events. The average (e and μ) b-quark semileptonic branching ratio has been determined to be BR (b → ℓ + X) = 0.119 ± 0.003 (stat.) ± 0.006 (syst.), assuming the standard model prediction of Γbb = 378 ± 3 MeV. From the ratio of the number of dilepton events to single lepton events, we find BR (b → ℓ + X) = 0.113 ± 0.010 (stat.) ± 0.006 (syst.), without assumptions on Λbb. The partial decay width of the Z0 into has been measured to be Λbb = 385 ± 7 (stat.) ± 11 (syst.) MeV with an additional 19 MeV error from the uncertainty in BR (b → ℓ + X). The average fractional energy of bottom hadrons in events has been determined to be 〈xE〉 = 0.686 ± 0.006 (stat.) ± 0.016 (syst.)., Facultad de Ciencias Exactas

Abstract: We present a study of energy-energy correlations based on 83 000 hadronic Z0 decays. From this data we determine the strong coupling constant αs to second order QCD: αs(91.2 GeV)=0.121±0.004(exp.)±0.002(hadr.)-0.006 + 0.009(scale)±0.006(theor.) from the energy-energy correlation and αs(91.2 GeV)=0.115±0.004(exp.)-0.004 +0.007(hadr.) -0.000 +0.002(scale)- 0.005 +0.003 (theor.) from its asymmetry using a renormalization scale μ1=0.1 s. The first error (exp.) is the systematic experimental uncertainly, the statistical error is negligible. The other errors are due to hadronization (hadr.), renormalization scale (scale) uncertainties, and differences between the calculated second order corrections (theor.). © 1991.

Abstract: We have searched for direct leptoquark production in Z0 decays from a scan of the Z0 resonance, in the energy range 88.2 ⩽ √s ⩽ 94.2 GeV, using 5.2 pb−1 of data. We exclude the existence of scalar leptoquarks with masses less than 41 to 44 GeV, depending on the charge assignments, at the 95% confidence level.

Abstract: From a fit to the impact parameter distribution of lepton tracks from semileptonic b decay, the lifetime of B-hadrons produced in e + e − collisions at the Z 0 is measured to be 1.32±0.08 (stat.)±0.09(syst.) ps. Combined with an earlier measurement of the branching ratio Br(B→l ν X), the CKM matrix element | V cb | is determined to be 0.046±0.002 (exp.) −0.003 +0.004 (theory).

Abstract: We have searched for lepton flavour violation in Z0 boson decays into lepton pairs, Z0→μτ, Z0→eτ, and Z0→eμ. The data sample is based on an integrated luminosity of 10.4 pb-1 corresponding to 370 000 Z0’s produced. We obtain upper limits on the branching ratios of 4.8 X 10-5 for the μτ 3.4 X 10-5 for the eτ and 2.4 X 10-5 for the eμ decay modes at the 95% confidence level., Facultad de Ciencias Exactas

Abstract: We have studied the reactions e+e−→hadrons, e+e−, μ+ μ− and τ+τ−, in the energy range 88.2 ≦ √s ≦ 94.2 GeV. A total luminosity of 5.5 pb−1, corresponding to approximately 115000 hadronic and 10000 leptonic Z0 decays, has been recorded with the L3 detector. From a simultaneous fit to all of our measured cross section data, we obtain assuming lepton universality: Mz = 91.181 ± 0.010 ± 0.02 (LEP) GeV, Γz = 2501 ± 17 MeV, Γhad= 1742 ± 19 MeV, Γt = 83.6 ± 0.8 MeV. If we do not assume lepton universality, we obtain for the partial decay widths of the Z0 into e+e−, μ+μ− and τ+ τ−: Γe = 83.3 ± 1.1 MeV, Γμ = 84.5 ± 2.0 MeV, Γτ = 84.0 ± 2.7 MeV. From the measured ratio of the invisible and the leptonic decay widths of the Z0, we determine the number of light neutrino species to be Nv =3.05±0.10. We include our measurements of the forward-backward asymmetry for the leptonic channels in a fit to determine the vector and axial-vector neutral current coupling constants of charged leptons to the Z0. We obtain g¯V = −0.046+0.015−0.012 and g¯A = −0.500 ± 0.003. In the framework of the Standard Model, we estimate the top quark mass to be mt =193+52−69 ± 16 (Higgs) GeV, and we derive a value for the weak mixing angle of sin2θW ≡ 1 − (MW/MZ)2 = 0.222 ± 0.008, corresponding to an effective weak mixing angle of sin2θ¯W = 0.2315 ± 0.0025., Facultad de Ciencias Exactas

Abstract: We have measured the cross-section of the reaction e + e − → γγ at center of mass energies around the Z 0 mass. The results are in good agreement with QED predictions. For the QED cutoff parameters the limit of Λ + > 103 GeV and Λ − 118 GeV are found. For the decays Z 0 → γ ,Z 0 → π 0 γ , Z 0 → γγγ we find upper limits of 2.9 × 10 −4 ,2.9×10 −4 ,4.1×10 −4 and 1.2×10 −4 , respectively. All limits are at 95% CL.

Abstract: We present the results from a search for the light neutral scalar Higgs boson h° and the pseudoscalar Higgs boson A° of the minimal super-symmetric standard model. The analysis is based on a data sample corresponding to 71 000 hadronic Z° decays recorded with the L3 detector at LEP. No evidence for the existence of the neutral Higgs bosons h° and A° has been found. The region of h° and A° masses up to 41.5 GeV is excluded at 95% confidence level.

Abstract: We searched for excited electrons and muons from Z 0 decay in the channels ee→eeγ, ee→eeγγ, ee→(e)eγ, ee→μμγ, ee→μμγγ. using the L3 detector at LEP. The lower mass limit for e ∗ is 45.0 GeV and for μ ∗ 45.3 GeV. The upper limits of ll ∗ Z 0 and ll ∗ γ couplings at 95% CL have been determined up to m l∗ close to the Z 0 mass.

Abstract: We have measured the properties of Z0 → b b decays using a sample of 944 inclusive muon events, corresponding to 18 000 hadron events obtained with the L3 detector at LEP. We measured the partial decay width of the Z0 into b b , Γ b b =353±48 MeV , and we determined the vector coupling of the Z0 to the b quark; grmv2(b)=0.095±0.047. We measured the forward-backward charge asymmetry in e+e− → b b events at √s≈Mv, and obtained A b b =13.3±9.9% .

Abstract: If simplified, every information retrieval problem can be solved when the information need implied by its expression has been identified. We are interested in the criteria used in realising a good information retrieval problem expression. We have listed these criteria through some principles and maxims which first characterized the communication between two persons are applied. We choose to use the gricean maxims because they are the most favoured for this type of situation. Secondly, we have tried to identify some others principles that can be used to realise a good information retrieval problem expression. The principles by Grice can not resolve all forms of error associated with this particular form of communication. In our work, we defined three other principles namely: adhesion principle, reformulation principle, memorization principle. We give some examples of situations where the principles we have formulated are not applicable and the consequences. We present the possible applications of our new model: MIRABEL, which can help in the description of information retrieval problem from. It also compels its user to use essential good expression principle implicitly.

Abstract: We have measured the partial widths for the three reactions e + e − → Z 0 → e + e − , μ + μ − , τ + τ − . The results are Γ ee = 84.3±1.3 MeV, √ Γ ee Γ μμ =83.9±1.4 MeV, and √ Γ ee Γ ττ =83.9±1.4 MeV, where the errors are statistical. The systematic errors are estimated to be 1.0 MeV, 0.9 MeV, and 1.4 MeV, respectively. We perform a simultaneous fit to the cross sections for the e + e − →e + e − , μ + μ − , and τ + τ − data, the differential cross section as a function of polar angle for the electron data, and the forward- backward asymmetry for the muon data. We obtain the leptonic partial with Γ ll =84.0±0.9 (stat.) MeV. The systematic error is estimated to be 0.8 MeV. Also, we obtain the axial-vector and vector weak coupling constants of charged leptons, g A =−0.500±0.003 and g ν =−0.064 −0.013 +0.017 .

Abstract: A search for the neutral Higgs boson, using the processes Z 0 → H 0 e + e − , Z 0 → H 0 μ + μ − , Z 0 → H 0 τ + τ − , Z 0 → H 0 v v and Z 0 → H 0 q q , is performed on data collected by the ALEPH detector corresponding to about 11 550 events of Z0 → hadrons. Combining all these processes, the mass range excluded is 32 MeV−15 GeV at 95% CL and 40 MeV−12 GeV at 99% CL. The result from this experiment is unambiguous in the context of the standard model.

Abstract: Anatomy is increasingly taught using computer-assisted learning tools, including electronic interactive anatomy dissection tables. Anatomage was he first virtual anatomy dissection table introduced in Russian medical universities and gained popularity among lecturers and students. The Pirogov interactive anatomy table was recently released, but the strengths and weakness of each platform is currently unknown. The objective of this article is to survey lecturers in anatomy to understand their perspectives on the Pirogov versus Anatomage virtual dissection tables' application to teaching in medical universities. A total of 80 anatomy educators from 12 Russian universities, using Anatomage (n = 40) and Pirogov (n = 40) tables were surveyed regarding their satisfaction with the application of the respective tables. Using a five-point Likert scale, both tables were assessed, and responses were statistically analyzed. In addition, qualitative analysis was performed on free response comments provided by survey respondents. There was no significant difference in overall satisfaction ratings between Pirogov (4.38 ± 0.53) and Anatomage (3.94 ± 0.60) interactive tables (p > 0.05). The Anatomage table ranked significantly higher on the accuracy of displayed anatomical details, resolution of the images, and its suitability for teaching senior medical and postgraduate students. Pirogov table performed significantly better on survey items measuring ergonomics, ability to assess students' performance, and teaching basic anatomy to junior first- and second-year medical students. Thus, in summary, anatomists' responses indicated that while both tables are suitable for teaching anatomy, the Pirogov table was superior in undergraduate medical education and the Anatomage table was more beneficial for teaching more senior trainees., (© 2022 American Association for Anatomy.)

Abstract: The MuCap experiment at the Paul Scherrer Institute has measured the rate Λ(S) of muon capture from the singlet state of the muonic hydrogen atom to a precision of 1%. A muon beam was stopped in a time projection chamber filled with 10-bar, ultrapure hydrogen gas. Cylindrical wire chambers and a segmented scintillator barrel detected electrons from muon decay. Λ(S) is determined from the difference between the μ(-) disappearance rate in hydrogen and the free muon decay rate. The result is based on the analysis of 1.2 × 10(10) μ(-) decays, from which we extract the capture rate Λ(S) = (714.9 ± 5.4(stat) ± 5.1(syst)) s(-1) and derive the proton's pseudoscalar coupling g(P)(q(0)(2) = -0.88 m(μ)(2)) = 8.06 ± 0.55.

Abstract: The rate of nuclear muon capture by the proton has been measured using a new technique based on a time projection chamber operating in ultraclean, deuterium-depleted hydrogen gas, which is key to avoiding uncertainties from muonic molecule formation. The capture rate from the hyperfine singlet ground state of the microp atom was obtained from the difference between the micro(-) disappearance rate in hydrogen and the world average for the micro(+) decay rate, yielding Lambda(S)=725.0+/-17.4 s(-1), from which the induced pseudoscalar coupling of the nucleon, g(P)(q(2)=-0.88m(2)(micro))=7.3+/-1.1, is extracted.

Abstract: Destruction of guard cell nuclei in epidermis isolated from leaves of pea, maize, sunflower, and haricot bean, as well as destruction of cell nuclei in leaves of the aquatic plants waterweed and eelgrass were induced by cyanide. Destruction of nuclei was strengthened by illumination, prevented by the antioxidant alpha-tocopherol and an electron acceptor N,N,N ,N -tetramethyl-p-phenylenediamine, and removed by quinacrine. Photosynthetic O2 evolution by the leaf slices of a C3 plant (pea), or a C4 plant (maize) was inhibited by CN- inactivating ribulose-1,5-bisphosphate carboxylase, and was renewed by subsequent addition of the electron acceptor p-benzoquinone.

Abstract: We report the first observation of a charm-strange meson D(+)(sJ)(2632) at a mass of 2632.5+/-1.7 MeV/c(2) in data from SELEX, the charm hadro-production experiment E781 at Fermilab. This state is seen in two decay modes, D(+)(s)eta and D0K+. In the D(+)(s)eta decay mode we observe a peak with 101 events over a combinatoric background of 54.9 events at a mass of 2635.4+/-3.3 MeV/c(2). There is a corresponding peak of 21 events over a background of 6.9 at 2631.5+/-2.0 MeV/c(2) in the decay mode D0K+. The decay width of this state is <17 MeV/c(2) at 90% confidence level. The relative branching ratio Gamma(D0K+)/Gamma(D(+)(s)eta) is 0.14+/-0.06. The mechanism that keeps this state narrow is unclear. Its decay pattern is also unusual, being dominated by the D(+)(s)eta decay mode.

Abstract: We observe a signal for the doubly charmed baryon Xi(+)(cc) in the charged decay mode Xi(+)(cc)-->Lambda(+)(c)K-pi(+) in data from SELEX, the charm hadroproduction experiment at Fermilab. We observe an excess of 15.9 events over an expected background of 6.1+/-0.5 events, a statistical significance of 6.3sigma. The observed mass of this state is 3519+/-1 MeV/c(2). The Gaussian mass width of this state is 3 MeV/c(2), consistent with resolution; its lifetime is less than 33 fs at 90% confidence.

Abstract: We report new precision measurements of the lifetimes of the Lambda(+)(c) and D0 from SELEX, the charm hadroproduction experiment at Fermilab. Based upon 1630 Lambda(+)(c) and 10 210 D0 decays we observe lifetimes of tau[Lambda(+)(c)] = 198.1+/-7.0+/-5.6 fs and tau[D0] = 407.9+/-6.0+/-4.3 fs.

Abstract: We report the first observation of the Cabibbo-suppressed charm baryon decay Ξ_{c}^{+}→pK^{-}π^{+}. We observe 150±22±5 events for the signal. The data were accumulated using the SELEX spectrometer during the 1996-1997 fixed target run at Fermilab, chiefly from a 600 GeV/c Σ^{-} beam. The branching fractions of the decay relative to the Cabibbo-favored Ξ_{c}^{+}→Σ^{+}K^{-}π^{+} and Ξ_{c}^{+}→Ξ^{-}π^{+}π^{+} are measured to be B(Ξ_{c}^{+}→pK^{-}π^{+})/B(Ξ_{c}^{+}→Σ^{+}K^{-}π^{+})=0.22±0.06±0.03 and B(Ξ_{c}^{+}→pK^{-}π^{+})/B(Ξ_{c}^{+}→Ξ^{-}π^{+}π^{+})=0.20±0.04±0.02, respectively.
