摘要：

We evaluate, in the high-energy limit, the sum of the Feynman amplitudes corresponding to the six two-loop ladder-like diagrams in Bhabha scattering. This is the limit where s --> infinity, while t, the electron mass m and the photon mass lambda are all being held fixed. In this limit the sum of the six Feynman amplitudes does not depend on the electron mass. When specialized to the region s >> Absolute value of t >> m2 >> lambda2 this result complements the one previously obtained. The connection with phi3 theory is also investigated.
