Two-parametric observables for Abelian $Z'$ searching in $p\bar{p}$ collisions at Tevatron energies
Abstract
We propose a scheme of searches for the Abelian gauge boson in the Drell-Yan process at TeV. We base our considerations on renor\-ma\-li\-za\-tion-group relations between the couplings to standard-model fermions. Considering the range of energies near the -boson peak, namely GeV for the invariant mass of a leptonic pair, we propose an integration scheme to construct two-parametric observables suitable for searches in the scattering. The observables allow to constrain the vector and axial-vector couplings to SM fermions in a general phenomenological parameterization with non-universal interactions with fermion generations. We also consider the cases of generation-universal boson and leptophobic boson, and show that one-parametric observables exist for these scenarios. The research is aimed to supplement direct searches for as an on-shell state in a specific set of new-physics models.
