Pairs of charged heavy-leptons from an SU(3) X U(1) model at CERN LHC
One of the versions of the SU(3)_L\otimesU(1)_N electroweak model predicts
charged heavy-leptons which do not belong to any class of heavy-leptons
proposed up to now. We investigate the production and signatures of pairs of
these heavy-leptons {\it via} the Drell-Yan process and the gluon-gluon fusion
at the CERN Large Hadron Collider (LHC). As an example we study the decay of
the exotic leptons into another ones. We see that the lifetime of the exotic
leptons can be short.Comment: 12 pages, 8 figures, Revtex4, Version published in Nucl. Phys.
Doubly charged Higgs from - scattering in the 3-3-1 Model
We studied the production and signatures of doubly charged Higgs bosons in
the process , where is a heavy lepton,
at the International Linear Collider (ILC) and CERN Linear Collider
(CLIC). The intermediate photons are given by the Weizscker-Williams
and laser backscattering distributions. We found that significant signatures
are obtained by bremsstrahlung and backward Comptom scattering of laser. A
clear signal can be obtained for doubly charged Higgs bosons, doubly charged
gauge bosons and heavy leptons
Pair of Heavy-Exotic-Quarks at LHC
We study the production and signatures of heavy exotic quarks pairs at LHC in
the framework of the vector singlet model (VSM), vector doublet model (VDM) and
fermion-mirror-fermion (FMF) model. The pair production cross sections for the
electroweak and strong sector are computed.Comment: 7 pages, 6 figures. accept at Int. Jour. of Mod. Phy
Searching for doubly charged Higgs bosons at the LHC in a 3-3-1 Model
Using a peculiar version of the SU(3)L x U(1)N electroweak model, we
investigate the production of doubly charged Higgs boson at the Large Hadron
Collider. Our results include branching ratio calculations for the doubly
charged Higgs and for one of the neutral scalar bosons of the model.Comment: 19 pages, 3 figure
Probing doubly charged Higgs in Colliders in 3-3-1 Model
The SU(3)_L\otimesU(1)_N electroweak model predicts new Higgs bosons beyond
the one of the standard model. In this work we investigate the signature and
production of doubly charged Higgs bosons in the International Linear
Collider and in the CERN Linear Collider. We compute the branching ratios for
the doubly charged gauge bosons of the model.Comment: 17 pages, 12 figure
Search for the Higgs Boson at LHC in 3-3-1 Model
We present an analysis of production and signature of neutral Higgs boson
() on the version of the 3-3-1 model containing heavy leptons at the
Large Hadron Collider. We studied the possibility to identify it using the
respective branching ratios. Cross section are given for the collider energy,
14 TeV. Event rates and significances are discussed for two
possible values of integrated luminosity, 300 fb and 3000 fb.Comment: 17 pages 7 figures. arXiv admin note: substantial text overlap with
