Title: Study of B{sub s}{yields}{pi}{rho} decays in the perturbative QCD approach

Abstract

In this note, we calculate the branching ratio and CP asymmetry parameters of B{sub s}{yields}{pi}{rho} in the framework of perturbative QCD approach based on k{sub T} factorization. This decay can occur only via annihilation diagrams in the standard model. We find that (a) the charge averaged Br(B{sub s}{yields}{pi}{sup +}{rho}{sup -}+{pi}{sup -}{rho}{sup +}) is about (9-12)x10{sup -7}; Br(B{sub s}{yields}{pi}{sup 0}{rho}{sup 0}){approx_equal}4x10{sup -7}; and (b) there are sizable CP asymmetries in the processes, which can be tested in the near future Large Hadron Collider beauty experiments (LHC-b) at CERN.
