Possibilities for charged Higgs bosons at the LHC in a SU(3)$_L\otimesU(1)_N$ Model
J. E. Cieza Montalvo, Nelson V. Cortez, J. Sá Borges +1
We have studied the branching ratios of doubly charged Higgs bosons at the LHC using a version of the SU(3)$_L\otimesU(1)_N$ electroweak model. At the end of this work we have made…
Signatures of Double Charged Higgs in model
J. E. Cieza Montalvo, Nelson V. Cortez, Mauro D. Tonasse
The scalar sector of the simplest version of the 3-3-1 electroweak models is constructed with three Higgs triplets only. We show that a relation involving two of the constants of t…
Searching for doubly charged Higgs bosons at the LHC in a 3-3-1 Model
J. E. Cieza Montalvo, Nelson V. Cortez, J. Sa Borges +1
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 bran…
and vertices in a QCD Sum Rule approach
M. E. Bracco, A. Cerqueira, M. Chiapparini +2
We calculate the strong form factors and coupling constants of and vertices using the QCD sum rules technique. In each case we have considered two differen…
Extension of the Nambu--Jona-Lasinio model at high densities and temperatures by using an implicit regularization scheme
R. L. S. Farias, G. Dallabona, G. Krein +1
Traditional cutoff regularization schemes of the Nambu--Jona-Lasinio model limit the applicability of the model to energy-momentum scales much below the value of the regularizing c…
