Available in PDF, EPUB and Kindle. Book excerpt: We have observed new channels for[tau] decays with an[eta] in the final state. We study 3-prong tau decays, using the[eta][yields][gamma][gamma] and[eta][yields] 3[pi][sup 0] decay modes and 1-prong decays with two[pi][sup 0]'s using the[eta][yields][gamma][gamma] channel. The measured branching fractions are[Beta]([tau][sup -][yields][pi][sup -][pi][sup -][pi][sup+][eta][nu][sub[tau]])= (3.4[sub -0.5][sup+0.6][+-] 0.6) x 10[sup -4] and[Beta]([tau][sup -][yields][pi][sup -]2[pi][sup 0][eta][nu][sub[tau]])= (1.4[+-] 0.6[+-] 0.3) x 10[sup -4]. We observe clear evidence for f[sub 1][yields][eta][pi][pi] substructure and measure[Beta]([tau][sup -][yields] f[sub 1][pi][sup -][nu][sub[tau]])= (5.8[sub -1.3][sup+1.4][+-] 1.8) x 10[sup -4]. We have also searched for[eta][prime](958) production and obtain 90% CL upper limits[Beta]([tau][sup -][yields][pi][sup -][eta][prime][nu][sub[tau]])

Download or read book Study of High Multiplicity 3-prong [tau] Decays at BaBar written by Mateusz Jerzy Lewczuk and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents measurements of the branching fractions for tau decays to 3-prong final states using a data set of 430 million tau lepton pairs, corresponding to an integrated luminosity of 468 fb-1, collected with the BaBar detector at the PEP-II asymmetric energy e+e- storage rings. The tau- -> (3pi)- eta nu_tau, tau^- ->pi- 2pi0 omega nu_tau and tau- -> f_1(1285) pi- nu_tau branching fractions are presented as well as a measurement of the non-resonant component of the tau- -> 3pi- 3pi0 nu_tau decay. In addition this work sets a new limit on the branching fraction of the isospin-forbidden, second-class current decay tau- -> pi- eta'(958) nu_tau.

Available in PDF, EPUB and Kindle. Book excerpt: Using the CLEO II detector at the e[sup+]e[sup -] storage ring CESR, we have determined the Michel parameters[rho], [zeta], and[delta] in[tau][sup[-+]][nu][bar[nu]] decay as well as the[tau] neutrino helicity parameter H[sub[nu][sub[tau]]] in[tau][sup[-+]][pi][sup 0][nu] decay. From a data sample of 3.02 x 10[sup 6][tau] pairs produced at[radical]s= 10.6 GeV, using events of the topology e[sup+]e[sup -][yields][tau][sup+][tau][sup -][yields] (l[sup[+-]][nu][bar[nu]])([pi][sup[-+]][pi][sup 0][nu]) and e[sup+]e[sup -][yields][tau][sup+][tau][sup -][yields] ([pi][sup[+-]][pi][sup 0][bar[nu]])([pi][sup[-+]][pi][sup 0][nu]), and the determined sign of h[sub[nu][sub[tau]]][1,2], the combined result of the three samples is:[rho]= 0.747[+-] 0.010[+-] 0.006, [zeta]= 1.007[+-] 0.040[+-] 0.015, [zeta][delta]= 0.745[+-]0.026[+-]0.009, and h[sub[nu][sub[tau]]]= -0.995[+-] 0.010[+-] 0.003. The results are in agreement with the Standard Model V-A interaction.

Book Synopsis A First Measurement of the Interaction Cross-section of the Tau Neutrino by :
Download or read book A First Measurement of the Interaction Cross-section of the Tau Neutrino written by and published by . This book was released on 2007 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The DONuT experiment collected data in 1997 and published first results in 2000 based on four observed [nu]{sub {tau}} charged-current (CC) interactions. The final analysis of the data collected in the experiment is presented in this paper, based on 3.6 x 1017 protons on target using the 800 GeV Tevatron beam at Fermilab. The number of observed [nu]{sub {tau}} CC interactions is 9, from a total of 578 observed neutrino interactions. We calculated the energy-independent part of the tau-neutrino CC cross section ([nu] + {bar [nu]}), relative to the well-known [nu]{sub e} and [nu]{sub {mu}} cross sections. The ratio [sigma]([nu]{sub {tau}})/[sigma]([nu]{sub e, {mu}}) was found to be 1.37 ± 0.35 ± 0.77. The {nu}{sub {tau}} CC cross section was found to be 0.72 ± 0.24 ± 0.36 x 10−38 cm2 GeV−1. Both results are in agreement with expectations from the Standard Model.
