Three-loop massive form factors: complete light-fermion and large-N c corrections for vector, axial-vector, scalar and pseudo-scalar currents
Abstract We compute the three-loop QCD corrections to the massive quark form factors with external vector, axial-vector, scalar and pseudo-scalar currents. All corrections with closed loops of massless fermions are included. The non-fermionic part is computed in the large-N c limit, where only plana...

All corrections with closed loops of massless fermions are included. The non-fermionic part is computed in the large-N c limit, where only planar Feynman diagrams contribute. |
