Nv. Zverev et Aa. Slavnov, A PARTIAL RESUMMATION OF DIAGRAMS IN THE 2-DIMENSIONAL LATTICE FERMION MODEL WITH PAULI-VILLARS REGULARIZATION, Theoretical and mathematical physics, 106(3), 1996, pp. 328-332
The polarization operator and axial current are obtained by means of a
partial resummation in the Schwinger two-dimensional lattice SLAC-fer
mion model with Pauli-Villars regularization. It is shown that the res
ummation procedure does not change the result obtained earlier in [1]
for the fermion model tinder consideration.
