Bestimmung einer oberen Grenze fur die Masse des tau-Neutrinos mit dem OPAL-Detektor
An upper limit for the tau -neutrino mass has been determined from the decay tau to 5 pi /sup +or-/ nu /sub tau / using data collected with the OPAL detector from 1991 to 1995 in e/sup +/e/sup -/ collisions at square root (s) $9 approximately=M/sub Z0/. A limit of 43.2 MeV at 95Ø.000554330L is obta...
