Bilepton production at hadron colliders - art. no. 075006

We examine, as model-independently as possible, the production of bileptons at hadron colliders. When a particular model is necessary or useful, we ch oose the 3-3-1 model. We consider a variety of processes: q (q) over bar -- >Y++Y--, u (d) over bar-->Y++Y-, (u) over bar d-->Y+Y--, q (q) over bar-->Y (++)e(-)e(-), q (q) over bar-->phi(++)phi(--), u (d) over bar-->phi(++)phi( -), and (u) over bar d -->phi(+)phi(--), where Y and phi are vector and sca lar bileptons, respectively. Given the present low-energy constraints, we f ind that, at the Fermilab Tevatron, vector bileptons are unobservable, whil e Light scalar bileptons (M(phi)less than or similar to 300 GeV) are just b arely observable. At the CERN LHC, the reach is extended considerably: vect or bileptons of mass M(Y)less than or similar to 1 TeV are observable, as a re scalar bileptons of mass M(phi)less than or similar to 850 GeV.
