Production of new chiral bosons at Tevatron and LHC

Abstract

The possibility of production of new spin-1 chiral particles at the hadron colliders the Tevatron and the LHC is considered. Their coupling constants to ordinary fermions can be fixed using the hypothesis about a dynamical generation of kinetic terms for the bosons and assuming an universality of interactions of these particles. The masses of the chiral particles can be predicted from experimental data of precise low-energy experiments, which already indicate indirectly the existence of such new particles. Quantitative estimations of the production cross-sections of the chiral particles are made. It is noteworthy that, due to their non-gauge interactions with fermions, their decays do not lead to the Jacobian peak in the transverse momentum/mass distribution. Moreover, the lightest chiral particles show leptophobic character, which makes their detection at hadron colliders challenging.
