I will discuss the Democratic Neutrino Theory and its origin from the level of composed leptons. This Theory has only one free parameter, unlike to 7 (9) free parameters in the conventional model of light Dirac (Majorana) neutrinos. In addition to the agreement with the results of Super Kamiokande, SNO, MINOS and other neutrino experiments, the discussed Theory sets the absolute scale of the...

In the first work, assuming lepton number conservation, hermiticity of the neutrino mass matrix and $\nu_{\mu} - \nu_{\tau}$ exchange symmetry, we show that we can determine the neutrino mass matrix completely from the existing data. This model predicts an inverted mass hierarchy (close to a degenerate pattern) with the three neutrino mass values, $8.91 \times 10^{-2}, 8.95 \times 10^{-2},...

Recently IceCube collaboration presented the evidence for high energy
extraterrestrial neutrinos, the nature of these neutrinos is still
unknown and opens the possibility to a new physics explanations.
In this talk I will present a geometric analysis trying to discriminate
between different explanations.

We present a generalization of a model where the right-handed up-type quarks serve as messengers for neutrino mass generation and as a portal for dark matter. Within this framework the Standard Model is extended with a single Majorana neutrino, a coloured electroweak-singlet scalar and a coloured electroweak-triplet scalar. We calculate the relic abundance of dark matter and show that we can...

In the inverse seesaw scenario, pseudo-Dirac neutrinos with mass at the electroweak scale
can have a sizable mixing with the Standard Model (SM) neutrinos, while providing the light neutrino masses through
a small lepton number violation. We study the production of the heavy neutrinos
through their mixing with the SM neutrinos at the Large Hadron collider (LHC).
Utilizing the search...

We investigate the production of a heavy Majorana neutrino with jets that arise from the U(1)_EM radiative corrections to the Drell-Yan mechanism at the CERN LHC. Preliminary results will be shown.

Starting from a scale-free electroweak sector at tree-level, we postulate that quantum effects of heavy right-handed neutrinos induce a mass term for a scalar weak doublet that contains the dark matter particle. In turn, below the scale of heavy neutrinos, the dark matter sector sets the scale of the Higgs potential. We show that this framework can lead to a Higgs mass that respects physical...
