Measurement of the -lepton mass with the Belle~II experiment
We present a measurement of the -lepton mass using a sample of about 175 million events collected with the Belle II detector at the SuperKEKB collider at a center-of-mass energy of . This sample corresponds to an integrated luminosity of . We use the kinematic edge of the pseudomass distribution in the decay and measure the tau mass to be 1777.09 MeV, where the first uncertainty is statistical and the second systematic. This result is the most precise to date.

a evo i da je 1776.9 MeV opet je validno, jer ne moze imati broj rijeci u decimalama, moras zaokruziti, i onda se zaokruzuje na 1777.
