Applicability of crossing symmetry in MG5

Asked by Patrick Rieck

Dear Mg5 developers,

I'm using MG5 autogenerated c++ code for standard model matrix elements. Clearly many amplitudes are related by crossing symmetry (like s<->t exchange). Is it possible to use an amplitude generated by MG5 for one process as the amplitude of any process related through crossing symmetry? This would involve negative energy momenta.

Many thanks in advance
Patrick
