Is there a particle that interacts with muons but not electrons?

This is a big if but if there is an unknown force that interacts with muons but not electrons then the following anomalies could be explained in one sweep: broken lepton universality proton size┬ábeing slightly larger when it is orbited … Continue reading

Lepton universality

  Electron, muon and tau are identical except for their invariant masses. They are identical with respect to the electromagnetic force because they carry the same electrical charge (-1). They are also identical with respect to the weak nuclear force … Continue reading
