Mirror matter, inverse seesaw neutrino masses and the Higgs mass spectrum

M. M. Candido, Y. A. Coutinho, P. C. Malta +2

In this work we study a mirror model with inverse seesaw neutrino masses in which symmetry breaking scales are fixed from bounds in the neutrino sector. The Higgs sector of the mod…

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…

Neutrino mixing in a left-right model

J. A. Martins Simoes, J. Ponciano

We study the mixing among different generations of massive neutrino fields in a gauge theory which includes Majorana and Dirac mass terms in…

Dirac and Majorana heavy neutrinos at LEP II

F. M. L. Almeida, Y. A. Coutinho, J. A. Martins Simões +2

The possibility of detecting single heavy Dirac and Majorana neutrinos at LEP II is investigated for heavy neutrino masses in the range . We study the pro…

Single neutral heavy lepton production at electron-muon colliders

F. M. L. Almeida, Y. A. Coutinho, J. A. Martins Simoes +1

New heavy Majorana and Dirac neutrinos production at future electron-muon colliders are investigated. The production of a single heavy neutrino is shown to be more relevant than pa…

Neutral heavy lepton production at next high energy linear colliders

F. M. L. Almeida, Y. A. Coutinho, J. A. Martins Simoes +1

The discovery potential for detecting new heavy Majorana and Dirac neutrinos at some recently proposed high energy colliders is discussed. These new particles are suggeste…
