Description
The general U$(1)_X$ extension of the Standard Model (SM) is a well motivated scenario which has a plenty of new physics options. Such a model is anomaly free which requires to add three generations of the SM singlet right-handed neutrinos (RHNs) which naturally generates the light neutrino masses by the seesaw mechanism.This offers interesting phenomenological aspects in the model. In addition to that the model is equipped with a beyond the SM (BSM) neutral gauge boson, $Z^\prime$ which interacts with the SM and BSM particles showing a variety of new physics driven signatures. After the anomaly cancellation the U$(1)_X$ charge of the particles are expressed in terms of the SM Higgs doublet and the SM Higgs singlet which allows us to study the interaction of the fermions with the $Z^\prime$.In this paper we investigate the pair production mechanism of the different charged through the photon, $Z$ and $Z^\prime$ boson exchange processes at the electron-positron $(e^- e^+)$.The angular distributions, forward-backward $(\mathcal{A}_{\rm{FB}})$, left-right $(\mathcal{A}_{\rm{LR}})$ and left-right forward-backward $(\mathcal{A}_{\rm{LR, FB}})$ asymmetries of the different charged fermion pair productions show substantial deviation from the SM results.
