Description

A comprehensive number of one-loop integrals in a theory with Wilson fermions at $r=1$ is computed using the Burgio--Caracciolo--Pelissetto algorithm. With the use of these results, the fermionic propagator in the coordinate representation is evaluated, making it possible to extend the Luscher-Weisz procedure for two-loop integrals to the fermionic case. Computations are performed with FORM and REDUCE packages.
