Abstract
We show that the reported anomalies in R(b) and R(c) can be interprete d as the effect of a heavy vector boson V universally coupled to u- an d d-type quarks separately and nearly decoupled from leptons. This ext ra vector boson could then also naturally explain the apparent excess of the jet rate at large transverse momentum observed at CDF.
