NNLL QCD Contribution of the Electromagnetic Dipole Operator to Gamma(anti-B -> X(s) gamma)

H. M. Asatrian, A. Hovhannisyan, V. Poghosyan +3

We present an independent calculation of that part of the O(α_s^2) contribution to the decay width Γ(\bar B -> X_s γ) which arises from the self-interference term of the electromag…

Reduction of Charm Quark Mass Scheme Dependence in at the NNLL Level

H. M. Asatrian, C. Greub, A. Hovhannisyan +2

The uncertainty of the theoretical prediction of the branching ratio at NLL level is dominated by the charm mass renormalization scheme ambiguity. In this paper…
