Abstract

We compute the two-loop QCD corrections to the heavy quark form factors in case of the vector, axial-vector, scalar and pseudo-scalar currents up to second order in the dimensional parameter ϵ=(4−D)/2\epsilon = (4-D)/2. These terms are required in the renormalization of the higher order corrections to these form factors.

Keywords
