Charge asymmetry in high-energy photoproduction in the electric field of a heavy atom
E. J. Downie, R. N. Lee, A. I. Milstein +1
The charge asymmetry in the differential cross section of high-energy photoproduction in the electric field of a heavy atom is obtained. This asymmetry arises due to the C…
LiteRed 1.4: a powerful tool for the reduction of the multiloop integrals
R. N Lee
We review the Mathematica package LiteRed, version 1.4.
Critical points and number of master integrals
Roman N. Lee, Andrei A. Pomeransky
We consider the question about the number of master integrals for a multiloop Feynman diagram. We show that, for a given set of denominators, this number is totally determined by t…
Four-loop corrections with two closed fermion loops to fermion self energies and the lepton anomalous magnetic moment
Roman Lee, Peter Marquard, Alexander V. Smirnov +2
We compute the eighth-order fermionic corrections involving two and three closed massless fermion loops to the anomalous magnetic moment of the muon. The required four-loop on-shel…
