Toward a NNLO calculation of the B-->X_s gamma decay rate with a cut on photon energy: I. Two-loop result for the soft function
Thomas Becher, Matthias Neubert
A theoretical analysis of the partial inclusive B-->X_s gamma decay rate with a cut E_gamma>E_0 on photon energy must deal with short-distance contributions associated with three d…
One-loop matching of Delta S=2 four-quark operators with improved staggered fermions
Thomas Becher, Elvira Gamiz, Kirill Melnikov
We compute O(alpha_s) lattice-to-continuum perturbative matching coefficients for the Delta S=2 flavor changing four-quark operators for the Asqtad improved staggered action. In co…
Factorization in B->V gamma Decays
Thomas Becher, Richard J. Hill, Matthias Neubert
The factorization properties of the radiative decays B->V gamma are analyzed at leading order in 1/m_b using the soft-collinear effective theory. It is shown that the decay amplitu…
