Abstract

We study the effect of large CP violating phases in the effective Supersymmetric theory and of Vector (i.e. SU(2) singlet) quarks on the rates and direct CP asymmetries in the decays B → X_dγ and B → X_sγ as well as on a combined sample. We show that while observing current experimental bounds, there is still a lot of room for substantial deviations from the Standard Model in the unmeasured quantities. Even if a direct measurement of B → X_dγ proves too difficult experimentally, its asymmetry contributes non-negligibly to the measurements of A_CP for B → X_sγ, and thus should be included in future analyses.
