Parity-Preserving Pauli-Villars Regularization in (2+1)-Dimensional Gauge Models

L. R. Baboukhadia, A. A. Khelashvili, N. A. Kiknadze

It is shown that, in QED${}_3$, the Pauli-Villars regularization involving a pair of auxiliary fermion fields with masses of opposite sign leads to results that are consistent with…
