Testing a possible W and Z structure at the LHC/CERN
F. M. L. de Almeida, H. Chavez, Y. A. Coutinho +4
One of the first channels to be experimentally analyzed at the LHC is . A resonance in this channel would be a clear indication of a new gau…
A left-right SU(7) symmetric model with D-parity cosmic strings
Helder Chavez S., J. A. Martins Simoes
Cosmic strings with the property of D-parity symmetry are studied in this paper. They are of a Z-2 type of strings that could appear in the spontaneous breaking of SU(7) and would…
Right-handed heavy neutrinos in the littlest Higgs model
F. M. L. de Almeida, Y. A. Coutinho, J. A. Martins Simões +3
In this paper we discuss the consequences of including a new heavy right-handed neutrino singlet in the littlest Higgs model. This new state is not connected with the light n…
Discriminating among the theoretical origins of new heavy Majorana neutrinos at the CERN LHC
F. M. L. de Almeida, Y. A. Coutinho, J. A. Martins Simoes +3
A study on the possibility of distinguishing new heavy Majorana neutrino models at LHC energies is presented. The experimental confirmation of standard neutrinos with non-zero mass…
Distinguishing Z' signatures and the Littlest Higgs model in e+e- Colliders at sqrt{s} \ne M_{Z'}
F. M. L. de Almeida, Y. A. Coutinho, J. A. Martins Simoes +3
There is a recent proposal identifying the Higgs particle of the Standard Model as a pseudo Nambu-Goldstone boson. This new broken symmetry introduces new particles and new interac…
The muon g-2 in a SU(7) left-right symmetric model with mirror fermions
H. Chavez, J. A. Martins Simoes
We have studied a left-right symmetric model with mirror fermions based in a grand unified SU(7) model in order to account for the muon anomaly. The Higgs sector of the model conta…
