Hi Marco,

I've done the following test with this branch:

import model loop_qcd_qed_sm_Gmu-a0
generate p p > !a! !a! [real=QCD] ; output ; launch -p -f

and it crashes stating that there are "no integration channels". Looking in the relevant gensym.log, there is "ERROR, too many photons 2". I thought that the above process should have worked, no? Have I misunderstood something here?

Best,
Rikkert
