CP violation induced by the double resonance for pure annihilation decay process in perturbative QCD
Abstract In a perturbative QCD approach we study the direct CP violation in the pure annihilation decay process of $$\bar{B}^0_{s}\rightarrow \pi ^+\pi ^-\pi ^+\pi ^-$$ B ¯ s 0 → π + π - π + π - induced by the $$\rho $$ ρ and $$\omega $$ ω double resonance effect. Generally, the CP violation is smal...
