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

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.
