Description
Hello,
I am looking at a BSM scenario where a final state particle is a heavy stable charged particle.I have treated it as a muon so that in my root file it is identified as a muon.If additionally I have actual muon in my final state I want to distinguish between them.Is there any accessible variable in Delphes 3 using which I can distinguish between them??

Hi,
what do you mean by "I have treated as a muon". How is it described in your LHE file?
Does it have muon pdgcode and mass? Could you please be more specific and maybe attach a SMALL lhe file describing what you did exactly?
Thanks
Michele

Hello,
Michele
Thank You for your reply.I have modified the DelphesSTDHEPReader.cc in a way so as to include the new particle in the array stableParticle and then in ParticlePropagator.cc I have added the particle in MuonArray.So that in output root file both muon and the new particle are read as "typ == 2".But the Mass and the pdg are never same as that of Muon.

Hi,
you can try to access to GenParticle counterpart of the muon by doing something like this:
https://github.com/delphes/delphes/blob/master/examples/Example3.C#L155-L156
this should give you access to variables like Pdg Code, Mass etc ...
Let me know if this works.

This is also working in 2022. Thanks for that.
