PaVe
PaVe[i, j, ..., {p10, p12, ...}, {m1^2, mw^2, ...}]
denotes the invariant (and scalar) Passarino-Veltman integrals, i.e. the coefficient functions of the tensor integral decomposition. Joining plist
and mlist
gives the same conventions as for A0
, B0
, C0
, D0
. Automatic simplifications are performed for the coefficient functions of two-point integrals and for the scalar integrals.
