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…

Virtual- and bremsstrahlung corrections to b -> d l+ l- in the standard model

H. M. Asatrian, K. Bieri, C. Greub +1

We present the calculation of the virtual- and bremsstrahlung corrections of O(alpha_s) to the matrix elements <d l+ l-|O_i|b>. This is the missing piece in the NNLL results for va…
