چکیده
The origin of neutrino mass is usually attributed to a seesaw mechanism, either through a heavy Majorana fermion singlet (version 1) or a heavy scalar triplet (version 2). Recently, the idea of using a heavy Majorana fermion triplet (version 3) has gained some attention. This is a review of the basic idea involved, its U(1) gauge extension, and some recent developments.

Here we review the main results of LFV in the semileptonic tau decays τ → μPP (PP = π+π−,π0π0,K+K−,K0K̄0), τ → μP (P = π,η,η ), and τ → μV (V = ρ,φ ) as well as in μ − e conversion in nuclei within SUSY-seesaw scenarios, and compare our predictions with the present experimental bounds1 .

We suggest a hybrid seesaw model where relatively “light” right-handed neutrinos give no contribution to the neutrino mass matrix due to a special symmetry. This allows their Yukawa couplings to the standard model particles to be relatively strong, so that the standard model Higgs boson can decay dominantly to a left and a right-handed neutrino, leaving another stable right-handed neutrino as c...

Several supersymmetric models with extended gauge structures predict light doubly-charged Higgsinos. Their distinctive signature at the large hadron collider is highlighted by studying their production and decay characteristics.

Our present knowledge of neutrinos can be summarized in terms of the “standard neutrino scenario”. Phenomenology of this scenario as well as attempts to uncover physics behind neutrino mass and mixing are described. Goals of future studies include complete reconstruction of the neutrino mass and flavor spectrum, further test of the standard scenario and search for new physics beyond it. Develop...

It has been suggested that future long baseline neutrino experiments such as so-called super-beams, beta-beams, neutrino factories will have great sensitivity to the third mixing angle θ13, the CP phase δ and the mass hierarchy sign(∆m31) (For a review, see, e.g., [1]). Just like at the B factories, experiments of high precision measurements will allow us not only to measure precisely the param...
