Puzzle of W Leptonic Decay Branching Fractions and Gauge Model of Generation Nonuniversality
Abstract
Lepton generation universality holds very well in Z decays, but appears to be violated in recent LEP data of W leptonic decay branching fractions. If this trend persists, a consistent and natural explanation is a model of generation nonuniversality, based on the gauge group SU(2)L X U(1)R X U(1)B-L.
