R$_{b}$, R$_{c}$ and jet distributions at the Tevatron in a model with an extra vector boson

We show that the reported anomalies in R_b and R_c can be interpreted as the effect of a heavy vector boson V universally coupled to u- and d-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 lar...

Sumario:We show that the reported anomalies in R_b and R_c can be interpreted as the effect of a heavy vector boson V universally coupled to u- and d-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.
