During my internship at CP3, I studied the production of trileptons at the LHC using MadGraph5 and FeynRules. I first computed the Standard Model backgrounds for two trilepton channels and then implemented three new physics models that give rise to such signatures: a model with diquarks and a heavy vector boson inspired by $E_6$ GUTs, a model with heavy quarks and gluons inspired by extra-dimensional theories and  a model inspired by supersymmetry. For each model, I computed the production rates for trileptons in a benchmark consistent with existing limits and that allows a clear separation from the background to show they have parameter space regions accessible at the LHC.
