New Third-family Flavor Physics: Vertex Corrections
Abstract
As described previously, a new massive gauge boson (X) coupling only to the third family produces a tantalizing pattern of deviations away from the standard model. These include increasing Gamma_b/Gamma_h and decreasing the alpha_s(M_Z) extracted from Gamma_h/Gamma_ell . We review the status of these X-Z mixing effects. We then calculate X boson induced vertex corrections to Z partial decay widths and to ttbar production in ppbar colliders.
