Four-loop singularities of the massless fermion propagator in quenched three-dimensional QED

A. F. Pikelner, V. P. Gusynin, A. V. Kotikov +1

We calculate the three- and four-loop corrections to the massless fermion propagator in three-dimensional quenched Quantum Electrodynamics with four-component fermions. The three-l…
