Pair Production of Heavy-Exotic-Fermions

Abstract

We study the production and signatures of heavy exotic fermion pairs in the framework of the vector singlet model (VSM), vector doublet model (VDM) and fermion-mirror-fermion (FMF) model. We show that the pair production cross sections are competitive with the ones for the single production of exotic fermions due to the exchange of a photon in the $s$ channel and to the vector component of the $Z$ - boson coupling to exotic fermions. We also exhibit some kinematical distributions.
