Study of $B_s\to \varphi ({\rho }^0,\omega )$ Decays in Standard Model and Family Non-universal $Z^{\prime }$ Model

Ying Li, Yue Sun, Zhi-Tian Zou

Within QCD factorization approach, we employ the new results of form factors of $B_s\to \varphi$ and calculate the branching fractions, CP asymmetries (CPAs) and polarization fractions…
