Contribution

It presents a novel calculation of one-loop chiral amplitudes for Moller scattering, including soft photon emission, with compact, divergence-free relations.

Findings

Amplitudes are consistent with renormalization group predictions.

Infrared divergence-free relations are derived.

Results agree with theoretical expectations.

Abstract

The high energy amplitudes of the large angles Moller scattering are calculated in frame of chiral basis in Born and 1-loop QED level. Taking into account as well the contribution from emission of soft real photons the compact relations free from infrared divergences are obtained. The expressions for separate chiral amplitudes contribution to the cross section are in agreement with renormalization group predictions.
