The Prediction of Mass of Z'-Boson from $b_q^0-b_q^0 bar$ Mixing

TL;DR

This paper estimates the mass of a hypothetical Z' boson using B_q^0-B_q^0 bar mixing data, considering new physics effects from Z and Z' mediated flavor-changing neutral currents, with implications for future collider experiments.

Contribution

It introduces a method to predict Z' boson mass from B meson mixing data, incorporating both Z and Z' mediated flavor-changing effects, advancing beyond previous models.

Findings

Estimated Z' boson mass within experimental reach

Inclusion of Z and Z' mediated FCNC effects

Potential for future detection at LHC and B-factories

Abstract

$B_q^0-B_^0 bar$ mixing offers a profound probe into the effects of new physics beyond the Standard Model. In this paper, $B_s^0-B_s^0 bar$ and $B_d^0-B_d^0 bar$ mass differences are considered taking the effect of both Z-and Z' -mediated flavour-changing neutral currents in the $B_q^0-B_q^0 bar$ mixing (q = d, s). Our estimated mass of Z' boson is accessible at the experiments LHC and B-factories in near future.
