Why "p p > h h " can not run?

Asked by Brian Wang on 2018-10-08

I want to know why "p p > h h " can not run.

Command "generate p p > h h" interrupted with error:
NoDiagramException : No amplitudes generated from process Process: g/u/c/d/s/u~/c~/d~/s~ g/u/c/d/s/u~/c~/d~/s~ > h h WEIGHTED=4 @1. Please enter a valid process

So "p p > h h [QCD]" is LO ?

Thanks very much!

Hi,

yes that's correct. This is a loop induced process.

Cheers,
