zero process in madgraph

Asked by Arvind on 2018-09-01

Hi

i am running madgraph to find plot mass vs cross section for scalar leptoquarks. But the proces is showing no results. i have checked the issues given in this link https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/FAQ-General-14.
This is the code I am using
import model /home/arvind/HEP/MG5_aMC_v2.6.3.2/models/BlqModel1_UFO
define pb = p b b~
define tax = ta+ ta-
define lqx = lq lq~
define vx = ve vm vt ve~ vm~ vt~
generate pb pb > lqx tax QCD=10 QED=10 QLD=10
output lqtax
launch

mass of lq is 1.000 something
please help

Did you use the default dynamical factorization scale?
This one implements a cut below 4 GeV^2
Since your process seem at quite low energy this might be the issue.

Otherwise your model is not part of our database (which includes all FR public models)
So I can not comment that much.

Cheers,

Olivier
