No amplitudes generated from process p p > lq lq~ (using the leptoquark model)
Hello,
I want to produce the leptoqurk and also to decay it, but there is some error in its generation:
MG5_aMC>generate p p > ltqk ltqk~
INFO: Checking for minimal orders which gives processes.
INFO: Please specify coupling orders to bypass this step.

Command "generate p p > ltqk ltqk~" interrupted with error:
NoDiagramException : No amplitudes generated from process Process: g/u/c/d/
Why is this not a valid process ? Please help.
Thanks,
Joydeep
