Pair Production of Heavy-Exotic-Fermions
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 ...

متن کاملExotic Fermions and Bosons in the Quartification Model
Exotic fermions of half-integral charges at the TeV energy scale are predicted by the quartification model of Babu, Ma, and Willenbrock. We add to these one copy of their scalar analogs and discuss the ensuing phenomenological implications, i.e. radiative contributions to lepton masses and flavor-changing leptonic decays. In the recently proposed [1] model of SU(3) quartification, the low-energ...
متن کاملMuon anomalous magnetic moment confronts exotic fermions and gauge bosons
We investigate the status of models containing exotic fermions or extra Z-like neutral gauge bosons in the light of recent BNL data on anomalous magnetic moment of muon. We find that it is possible to extract interesting bounds on the extra parameters introduced in this way. This is especially true if the new flavourchanging neutral currents are of the axial vector type. The recent result from ...
متن کاملWeak-singlet fermions: Models and constraints
We employ data from precision electroweak tests and collider searches to derive constraints on the possibility that weak-singlet fermions mix with the ordinary standard model fermions. Our findings are presented within the context of a theory with weak-singlet partners for all ordinary fermions and theories in which only third-generation fermions mix with weak singlets. In addition, we indicate...
