A recently derived approach to the tensor reduction of 5-point one-loop Feynman integrals expresses the tensor coefficients by scalar 1-point to 4-point Feynman integrals completely algebraically. In this Letter we derive extremely compact algebraic expressions for the contractions of the tensor integrals with external momenta. This is based on sums over signed minors weighted with scalar products...
We perform a new, recursive reduction of one-loop n-point rank R tensor Feynman integrals [in short: (n,R)-integrals] for n⩽6 with R⩽n by representing (n,R)-integrals in terms of (n,R−1)- and (n−1,R−1)-integrals. We use the known representation of tensor integrals in terms of scalar integrals in higher dimension, which are then reduced by recurrence relations to integrals in generic dimension. With...
