SU(3) flavor symmetry and CP violating rate differences for charmless B → PV decays -: art. no. 034018

We derive several relations between CP violating rate differences Delta(B-->PV) = Gamma(B-->PV)-Gamma((B) over bar-->(P) over bar (V) over bar) for charmless B-->PV decays in the standard model using SU(3) flavor symmetry. It is found that although the relations between branching ratios of Delta S = 0 and Delta S = -1 processes are complicated, there are simple relations independent of hadronic models between some of the Delta S = 0 and Delta S = -1 rate differences due to the unitarity property of the Kobayashi-Maskawa matrix, such as Delta(B-->pi(+)rho(-)) = -Delta(B-->pi(+)K*(-)), Delta(B -->pi(-)rho(+)) = -Delta(B-->K(-)rho(+)). SU(3) breaking effects are also estimated using the factorization approximation. These relations can be tested at B factories in the near future.
