$CP$ violation induced by the double resonance for pure annihilation decay process in Perturbative QCD

Gang Lü, Ye Lu, Sheng-Tao Li +1

In Perturbative QCD (PQCD) approach we study the direct $CP$ violation in the pure annihilation decay process of ${\bar{B}}_s^0\to {\pi }^{+}{\pi }^{-}{\pi }^{+}{\pi }^{-}$ induced by the $\rho$ and $\omega$ d…
