3-3-1 exotic quark search at CERN LEPII and LHC - art. no. 115001

The 3-3-1 electroweak model is the simplest chiral extension of the standar d model which predicts single and double charged bileptons and exotic quark s carrying -4/3 and 5/3 units of positron charge. In this paper we study th e possibility of the production and decay of one of these exotic quarks at the CERN LEPII and LHC colliders. For typical vector bilepton, exotic quark masses, and mixing angles we obtain between 20 and 750 events per year. An gular distributions are also presented. [S0556-2821(99)06419-X].
