Belle II Measurement Makes World Average Tau Mass Match Koide's Rule
We present a measurement of the τ-lepton mass using a sample of about 175 million e+e−→τ+τ− events collected with the Belle II detector at the SuperKEKB e+e− collider at a center-of-mass energy of 10.579GeV. This sample corresponds to an integrated luminosity of 190fb^−1. We use the kinematic...
אני בוחר בתשובה NO.
ומאחר שאני לא יכול להגיב שם אני אגיב כאן.
