Available in PDF, EPUB and Kindle. Book excerpt: Abstract: We report a study of [tau] lepton decays to three charged hadrons and a [pi]0. We use (7.56 +/- 0.15) fb −1 of data collected with the CLEO III detector at the Y (4S) resonance, which corresponds to a total of (6.90 +/- 0.14) x 106 [tau]-pairs. Using both a Ring Imaging Cherenkov (RICH) detector and measurement of specific ionization energy loss (dE/dx) for particle identification, we report the first observation of the decay [tau]− [right arrow] K−[omega][tau neutrino]. We report the first statistically significant measurements of the branching fractions for [tau]− [right arrow] K−[pi][pi]−[pi]0[tau neutrino] (excluding K0), [tau]− [right arrow] K−K[pi]−[pi]0[tau neutrino] and the first published upper limit for [tau]− [right arrow] K−K+K−[pi]0[tau neutrino]. We also measure branching fractions for the decays, [tau]− [right arrow] h−[omega][tau neutrino], [tau]− [right arrow] [pi]−[omega][tau neutrino], [tau]− [right arrow] h−h+h−[pi]0[tau neutrino], and [tau]− [right arrow] [pi]−[pi]+[pi]−[pi]0[tau neutrino].

Download or read book Decays of the Heavy Lepton, Tau (1785). written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The structure of the weak hadronic current coupled to the tau is investigated via some of the hadronic decays of the tau. The vector current coupling is determined by measuring the tau .-->. rho .nu./sub tau/ branching ratio. The axial-vector coupling is determined by measuring the tau .-->. .pi. .nu./sub tau/ branching ratio. The Cabibbo structure of the hadronic current is established by observing the decay tau .-->. K*(890).nu./sub tau/ and measuring its branching ratio. The branching ratios for the decays tau .-->. e anti .nu./sub e/.nu./sub tau/ and tau .-->. .mu. anti .nu./sub .mu./.nu./sub tau/ are measured as a normalization for the hadronic decays and as a check on the validity of the measurements. The leptonic branching ratios agree well with previous experiments. From a kinematic fit to the pion energy spectrum in the decay tau .-->. .pi. .nu./sub tau/, an upper limit (95% confidence level) of 245 MeV is placed on the tau neutrino mass. From a simultaneous fit of the center of mass energy dependence of the tau production cross section and the pion energy spectrum in the decay tau .-->. .pi. .nu./sub tau/, the tau mass is determined to be 1.787 +- 010 GeV/c. All properties of the tau measured here are consistent with it being a sequential lepton coupled to the ordinary weak hadronic current.

Book Synopsis Search for Rare Multi-pion Decays of the Tau Lepton Using the BABAR Detector by : Ruben Ter-Antonyan
Download or read book Search for Rare Multi-pion Decays of the Tau Lepton Using the BABAR Detector written by Ruben Ter-Antonyan and published by . This book was released on 2006 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: A search for the decay of the tau lepton to rare multi-pion final states is performed using the BABAR detector at the PEP-II asymmetric-energy ee− collider. The analysis uses 232 fb−1 of data at center-of-mass energies on or near the Upsilon(4S) resonance. In the search for the tau− -> 5pi−2pi2pi0nu[tau] decay, we observe 10 events with an expected background of 6.5+2̇0−1.4 events. In the absence of a signal, we calculate the decay branching ratio upper limit B(tau− -> 5pi−2pi+2pi0nu[tau]) 3.4x10−6 at 90% confidence level. This is more than a factor of 30 improvement over the previously established limit. In addition, we search for the exclusive decay mode tau− - 2omega.pi−nu[tau] with the further decay of omega -> pi−pi+pi0. We observe 1 event, expecting 0.4+1̇0−0.4 background events, and calculate the upper limit B(tau− -> 2omega.pi−nu[tau])

Book excerpt: Reviews the current state of knowledge of neutrino masses and the related question of neutrino oscillations. After an overview of the theory of neutrino masses and mixings, detailed accounts are given of the laboratory limits on neutrino masses, astrophysical and cosmological constraints on those masses, experimental results on neutrino oscillations, the theoretical interpretation of those results, and theoretical models of neutrino masses and mixings. The book concludes with an examination of the potential of long-baseline experiments. This is an essential reference text for workers in elementary-particle physics, nuclear physics, and astrophysics.
