I have constructed a simple CMS detector in GEANT4 and I want to simulate p-p collision in it.
I have generated ASCII and .root files from Pythia and shooting those generated particles though G4ParticleGun.
But when quarks come in picture, it shows following error :
-------- WWWW ------- G4Exception-START -------- WWWW ------- *** G4Exception : Event0102 issued by : G4ParticleGun::SetParticleDefinition() G4ParticleGun does not support shooting a short-lived particle without a valid decay table. G4ParticleGun::SetParticleDefinition for u_quark is ignored.
Please let me know how to generate or assign decay table to a particle.
