Bilepton Production at Hadron Colliders

We examine, as model-independently as possible, the production of bileptons at hadron colliders. When a particular model is necessary or useful, we choose the 3-3-1 model. We consider a variety of processes: qq̄ → Y Y −−, ud̄ → Y Y −, ūd → Y Y −−, qq̄ → Y ++e−e−, qq̄ → φ++φ−−, ud̄ → φ++φ−, and ūd → φ+φ−−, where Y and φ are vector and scalar bileptons, respectively. Given the present low-energy constraints, we find that at the Tevatron, vector bileptons are unobservable, while light scalar bileptons (Mφ <∼ 300 GeV) are just barely observable. At the LHC, the reach is extended considerably: vector bileptons of mass MY <∼ 1 TeV are observable, as are scalar bileptons of mass Mφ <∼ 850 GeV.
