dc.description.abstractA limit on the tau neutrino mass M(nu)tau is obtained from a study of tau decays in the reaction e+e- --> tau+tau- at center-of-mass energies is similar to 10.6 GeV. The result is based on an end-point analysis of the invariant mass spectrum of the decay products in the decay modes tau- --> 3h-2h+nu(tau), and tau- --> 2h-h+2pi0nu(tau). The data sample used in this analysis contains 1.77 x 10(6) tau pairs, corresponding to an integrated luminosity of 1.92 fb-1, and is substantially larger than previous data samples used to place a limit on M(nu)tau. The limit obtained for both five-hadron modes together is 32.6 MeV at 95% C.L.
