Untagged B¯→Xs+dγ CP asymmetry as a probe for new physics

Furthermore, we derive general model-independent formulae for the branching ratios and CP asymmetries for the inclusive B¯→Xdγ and B¯→Xsγ modes, and update the corresponding SM predictions. We obtain for a photon energy cut-off E0=1.6GeV: B[B¯→Xsγ]=(3.61−0.40+0.24|mc/mb±0.02CKM±0.24param.±0.14scale)×10−4,ACP[B¯→Xsγ]=(0.42−0.08+0.08|mc/mb±0.03CKM−0.08+0.15|scale)%.
