CP asymmetry from the resonance effect of the B meson decay process with π and K final states*

Abstract

We present a novel $V\rightarrow K^{+}K^{-}$ $(V=\phi, \rho, \omega)$ resonance that generates a strong phase associated with vector meson resonances, leading to significant CP asymmetry in the interference region. The $\phi \rightarrow K^{+}K^{-}$, $\rho \rightarrow K^{+}K^{-}$ and $\omega \rightarrow K^{+}K^{-}$ resonances arise from the mixing of vector mesons $\phi$, $\rho$, $\omega$. We calculate the CP asymmetry from the decay modes of $B \rightarrow KK\pi(K)$. Meanwhile, the localised CP asymmetries are presented and some detailed analysis can be found. The CP asymmetry from the decay mode of ${B}^{-}\rightarrow \phi\pi^{-}\rightarrow K^{+}K^{-}\pi^{-}$ is also presented in our framework which is well consisted with LHC experiment. The introduced CP asymmetry can provide a favorable theoretical support for the experimental exploration in the future.
