Abstract: In the framework of Perturbative QCD (PQCD) approach we study the direct $CP$ asymmetry for the decay channel $\bar{B}_{s}\rightarrow P\pi^+\pi^-$ around the resonance range via the $\rho-\omega$ mixing mechanism (where P refer to pseudoscalar meson).… read more here.

Abstract: In this paper we calculate the $$\bar{B}_s \rightarrow f_0(980)$$ form factors from light-cone sum rules with B meson DAs. With adopting the quark–antiquark configuration of light scalar mesons, the high twist two-particle and the three-particle… read more here.
