OPITeR: A program for tensor reduction of multi-loop Feynman Integrals (2411.02233v2)

Published 4 Nov 2024 in hep-ph and hep-th

Abstract: We present OPITeR, a FORM program for the reduction of multi-loop tensor Feynman integrals. The program can handle tensors, including spinor indices, with rank of up to 20 and can deal with up to 8 independent external momenta. The reduction occurs in $D$ dimensions compatible with conventional dimensional regularization. The program is able to manifest symmetries of the integrand in the tensor reduced form.
