Rb, Rc and Jet Distributions at the Tevatron in a Model with an extra vector boson

High Energy Physics - Phenomenology 2011-01-25 v3

Abstract

We show that the reported anomalies in RbR_b and RcR_c can be interpreted as the effect of a heavy vector boson \zprime\ universally coupled to uu- and dd-type quarks separately and nearly decoupled from leptons. This extra vector boson could then also naturally explain the apparent excess of the jet rate at large transverse momentum observed at CDF.
