Family Non-universal $Z^{\prime }$ Effects on $B_{d,s}\to K^{\ast 0}{\overline{K}}^{\ast 0}$ Decays in Perturbative QCD Approach

Ying Li, Guo-Hua Zhao, Yan-Jun Sun +1

The nonleptonic decays $B_{d,s}\to K^{\ast 0}{\overline{K}}^{\ast 0}$ are reanalyzed in perturbative QCD approach, which is based on the $k_{\mathrm{T}}$ factorization. In the standard model,…
