Double seesaw mechanism in a left-right symmetric model with TeV neutrinos
F. M. L. de Almeida, Y. A. Coutinho, J. A. Martins Simões +4
A left-right symmetric model is discussed with new mirror fermions and a Higgs sector with two doublets and neutral scalar singlets. The seesaw mechanism is generalized, including…
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…
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…
On signatures for the Littlest Higgs model in electron-positron colliders
F. M. L. de Almeida, Y. A. Coutinho, J. A. Martins Simões +3
There is a recent proposal of identifying the Higgs particle of the Standard Model as a pseudo Nambu-Goldstone boson. This new broken symmetry introduces new particles and new inte…
