Can Family Gauge Bosons Be Visible by Terrestrial Experiments?

Abstract

It is investigated whether observations of family gauge bosons by terrestrial experiments are possible or not. We propose an extended version of Sumino's family gauge boson model based on U(3) family symmetry. Then, we can expect the lowest family gauge boson $A_1^1$ with $M\sim 4.3$ TeV.
