Query: Reduction of one-loop tensor 5-point integrals   A new method for the reduction of one-loop tensor 5-point integrals to
related 4-point integrals is proposed. In contrast to the usual
Passarino-Veltman reduction and other methods used in the literature, this
reduction avoids the occurrence of inverse Gram determinants, which potentially
cause severe numerical instabilities in practical calculations. Explicit
results for the 5-point tensor coefficients are presented up to rank 4. The
expressions for the reduction of the relevant 1-, 2-, 3-, and 4-point tensor
coefficients to scalar integrals are also included; apart from these standard
integrals no other integrals are needed.
