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 $(\mathcal{A}_{FB})$, left-right $(\mathcal{A}_{LR})$ and left-right forward-backward $(\mathcal{A}_{LR,FB})$ asymmetries of the different charged fermion pair productions show substantial deviation from the SM results.
