Forward-Backward Asymmetry in Two-Jet Events: Signature of Axigluons in Proton-Antiproton Collisions

摘要

Models of chiral colour suggest the existence of massive axigluons with strong couplings to quarks. Interference of gluon- and axigluon-induced amplitudes will give rise to a forward-backward asymmetry in qanti q -> Qanti Q which will be reflected in two-jet events containing a prompt lepton. We estimate this asymmetry for the CERN and Fermilab colliders. (ERA citation 13:008000)
