Two-Loop Matrix Element of the Current-Current Operator in the Decay B -> X_s gamma

Andrzej J. Buras, Andrzej Czarnecki, Mikolaj Misiak +1

We evaluate the important two-loop matrix element <s gamma| Q_2 | b> of the operator (cbar gamma^mu P_L b) (sbar gamma_mu P_L b) contributing to the inclusive radiative decay B ->…

Master Formulae for Delta F=2 NLO-QCD Factors in the Standard Model and Beyond

Andrzej J. Buras, Sebastian Jager, Joerg Urban

We present analytic formulae for the QCD renormalization group factors relating the Wilson coefficients C_i(mu_t) and C_i(mu), with mu_t = O(m_t) and mu < mu_t, of the Delta F=2 di…
