Penguin contribution to width difference and CP asymmetry in $B_{q}$ - $B ˉ_{q}$ mixing at order $α_{s}^{2} N_{f}$

Hrachia M. Asatrian, Hrachya H. Asatryan, Artyom Hovhannisyan +3

We present new contributions to the decay matrix element $Γ_{12}^{q}$ of the $B_{q}$ - $B ˉ_{q}$ mixing complex, where $q = d$ or $s$ . Our new results constitute the order $α_{s}^{2} N_{f}$ cor…

Rare decays $B ˉ \to X_{s (d)} γ$ at the NLO

H. M. Asatrian, H. H. Asatryan, A. Hovhannisyan

We present an independent calculation of $O (α_{s})$ matrix elements of the QCD penguin operators for the decays $B ˉ \to X_{s (d)} γ$ . The Mellin-Barnes representation techn…

Complete bremsstrahlung corrections to the forward-backward asymmetries in $b \to X_{s} ℓ^{+} ℓ^{-}$

H. M. Asatrian, H. H. Asatryan, A. Hovhannisyan +1

In a recent paper we presented a calculation of NNLL virtual corrections to the forward-backward asymmetries in $b \to X_{s} ℓ^{+} ℓ^{-}$ decay. That result does not include bremsstra…
