$CP$-violating observables in four-body $B\to \varphi (\to K\bar{K})K^{\ast }(\to K\pi )$ decays

Chao-Qi Zhang, Jia-Ming Li, Meng-Kun Jia +2

We analyse the four-body $B\to \varphi (\to K\bar{K})K^{\ast }(\to K\pi )$ decays in the perturbative QCD approach,where the invariant mass of $K\bar{K}$($K\pi$) system is limi…
