Update of the $\nu_{\tau}$ mass limit with 94 data
Update of the nu_tau mass limit with 94 data Adding the 1994 data to the 1991-93 sample for a total of 143,000 tau decays, the value of the limit on the tau neutrino mass has been updated. It slightly improves the published value [Phys.Lett.B 349(1995)585-586] to 23.1 MeV/c² at 95% confidence level...

| description | Update of the nu_tau mass limit with 94 data Adding the 1994 data to the 1991-93 sample for a total of 143,000 tau decays, the value of the limit on the tau neutrino mass has been updated. It slightly improves the published value [Phys.Lett.B 349(1995)585-586] to 23.1 MeV/c² at 95% confidence level. The sample of selected 5 pi(pi0) candidates consists now of 38 tau -> 5pi nu_tau and 3 tau -> 5pi-pi0 nu_tau. The compatibility with expectations from a tau -> a1 2pi nu_tau model increased from 5% to 10%. |
