The planar four-point master integrals for massive two-loop Bhabha scattering Original Research Article

We present the values of the complete set of planar four-point Master Integrals needed for massive Bhabha scattering in the limit of fixed angle and high energy at the two-loop level. The integrals have been calculated using direct expansions of Mellin–Barnes representations, followed by a resummation of resulting harmonic series.
