Decorated-box-diagram-contributions to Bhabha scattering. (II)

Abstract

We evaluate, in the high-energy limit, $s\gg |t|\gg m^2\gg {\lambda }^2$, the sum of amplitudes corresponding to a class of Feynman diagrams describing two-loop virtual photonic corrections to Bhabha scattering. The diagrams considered are box and crossed box diagrams with a vacuum polarization insertion in one of the photon lines.
