Study of $B\to K^{\ast }\rho ,K^{\ast }\omega$ Decays with Polarization in Perturbative QCD Approach

Han-Wen Huang, Cai-Dian Lu, Toshiyuki Morii +3

The $B\to K^{\ast }\rho$, $K^{\ast }\omega$ decays are useful to determine the CKM angle ${\varphi }_3=\gamma$. Their polarization fractions are also interesting since the polarization puzzle of the $B\to ϕK^…
