High Energy Physics - Phenomenology 2009-11-10 v2

Abstract

We compute the two-loop virtual corrections to the flavour changing neutral current process b>dl+lb --> d l^+ l^-. As calculation techniques integration by parts identities and the method of differential equations are used. The result is presented in closed form as a function of q2/mb2q^2/m_b^2, where q2q^2 is the invariant mass of the lepton pair and mbm_b is the b-quark mass.
