CP-Violation in b Quark Radiative Inclusive Decays

H. M. Asatrian, G. K. Yeghiyan, A. N. Ioannissian

The direct CP-violations in $S U (2)_{L} \times S U (2)_{R} \times U (1)$ model and two-Higgs doublet extension of the standard model for $b \to d γ$ and $b \to s γ$ decays are investigate…

CP-Violation in the Decay $b \to s γ$ in the Left-Right Symmetric Model

H. Asatrian, A. Ioannissian

The direct CP-violation in the left-right symmetric $S U (2) \times S U (2) \times U (1)$ model is investigated for the decay $b \to s γ$ . The calculated CP-asymmetry for the wid…

Long Distance Contribution to $s \to d γ$ and Implications for $Ω^{-} \to Ξ^{-} γ, B_{s} \to B_{d}^{*} γ$ and $b \to s γ$

G. Eilam, A. Ioannissian, R. R. Mendel +1

We estimate the long distance (LD) contribution to the magnetic part of the $s \to d γ$ transition using the Vector Meson Dominance approximation $(V = ρ, ω, ψ_{i})$ . We find that this co…

LONG DISTANCE EFFECTS AND CP VIOLATION in $B^{\pm} \to ρ^{\pm} γ$

G. Eilam, A. Ioannissian, R. R. Mendel

We demonstrate that the long distance contribution to $B^{\pm} \to ρ^{\pm} γ$ may have a large effect on the decay rate and through it on the CP violating partial rate asymmetry. T…

Effects of new physics in the rare decays $B \to K ℓ^{+} ℓ^{-}$ and $B \to K^{*} ℓ^{+} ℓ^{-}$

C. Greub, A. Ioannissian, D. Wyler

We parametrize phenomenologically possible new physics effects and calculate their influence on the invariant dilepton mass spectrum and the Dalitz plot for the decays $B \to K \el…
