Region analysis of QED massive fermion form factor

Region analysis of QED massive fermion form factor

Abstract We perform an analysis of the one- and two-loop massive quark form factor in QED in a region expansion, up to next-to-leading power in the quark mass. This yields an extensive set of regional integrals, categorized into three topologies, against which factorization theorems at next-to-leadi...
