failure to generate phase space

Asked by Hind

Hi,

I'm trying to simulate a simple 2-> 2 contact term pair production process, which keeps failing due to a "FATAL ERROR: Phase-space: generation failed" I'm unsure how to resolve this and haven't found much help in the manual. I have enough energy in sqrts for pair production, so that is not a problem.

Thanks!

To clarify: the process involves a 4 fermion interaction. Which may be why it is failing?

Hi,
exactly this case is discussed in Sec. 8.6 of the manual. Please let us know if that information is insufficent.
Best,
