Abstract

Physical Sciences Physics Physics, Nuclear Physics, Particles & Fields Science & Technology
We present an analytic calculation of Branching Ratio (BR) and ChargeParity (CP) violating asymmetries of the Bs0 meson decays to light vector mesons (K*0K*0) within the framework of Naive Factorization (NF) and QCD Factorization (QCDF). We find the BR(Bs0K*0K*0)=1.87x10-5 and 1.40 x 10(-5) for NF and QCDF, respectively. We also find that within QCDF the direct CP violation (ACPdir)=-0.01, CP violation in mixing (ACPmix)=0.31 and CP violation due to interference (A(CP)(Delta Gamma)=0.95.
