NNLO corrections to B --> X_u l nu in the shape-function region
H. M. Asatrian, C. Greub, B. D. Pecjak
The inclusive decay B --> X_u l nu is of much interest because of its potential to constrain the CKM element |V_ub|. Experimental cuts required to suppress charm background restric…
Charm quark mass dependence of the electromagnetic dipole operator contribution to anti-B -> X(s) gamma at O(alpha**2(s))
H. M. Asatrian, T. Ewerth, H. Gabrielyan +1
We extend existing calculations of the electromagnetic dipole operator contribution to the total decay rate and the photon energy spectrum of the decay \bar{B} -> X_sγat O(α_s^2) b…
Estimate of BR(B -> X_s gamma) at O(alpha_s^2)
M. Misiak, H. M. Asatrian, K. Bieri +14
Combining our results for various O(alpha_s^2) corrections to the weak radiative B-meson decay, we are able to present the first estimate of the branching ratio at the next-to-next…
Magnetic dipole operator contributions to the photon energy spectrum in anti-B -> X(s) gamma at O(alpha(s)^2)
H. M. Asatrian, T. Ewerth, A. Ferroglia +2
We compute the O(α_s^2) contributions to the photon energy spectrum of the inclusive decay \bar{B} -> X_s γassociated with the magnetic penguin operator O_7. They are an essential…
Rare decays at the NLO
H. M. Asatrian, H. H. Asatryan, A. Hovhannisyan
We present an independent calculation of matrix elements of the QCD penguin operators for the decays . The Mellin-Barnes representation techn…
Complete bremsstrahlung corrections to the forward-backward asymmetries in
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 decay. That result does not include bremsstra…
