New third-family flavor physics and the top mass
B. Holdom
Abstract
A new massive gauge boson (X) coupling to the third family produces a tantalizing pattern of deviations away from the standard model. These include increasing Gammab/Gammah and decreasing the alphas(MZ) extracted from Gammah/Gammaell. We indicate how the X boson may be related to a dynamical origin of the top mass.
