cuts for usr_v4 models

Asked by attilio santocchia

Hello,

I'm using a model implemented in usrmod_v4 and I'm ok with the generation... the problem I get is that when I use Delphes and the CMS card there is a cut on the minimum pt of leptons and a lot of events produced and showered by madgraph/pythia8 are not passing the minimum request of 2 muons. I'm trying to implement a very simple cut (pt minimum for the particle I defined in usrmod_v4... I used 130013 for its pdgid) but following the instruction in https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/FAQ-General-1 I don't see any reference to the pdgid of the particles... what is the suggested way to do it... or better, is there an example I can use as a reference?
Thanks

Attilio

Hi,

You can use the following line to check the pdg code
     if (abs(idup(i,1,iproc)).eq.130013)

Cheers,

Olivier
