Dirac neutrinos from Peccei-Quinn symmetry: a fresh look at the axion
Eduardo Peinado, Mario Reig, Rahul Srivastava +1
We show that a very simple solution to the strong CP problem naturally leads to Dirac neutrinos. Small effective neutrino masses emerge from a type I Dirac seesaw mechanism. Neutri…
Fermion Dark Matter and Radiative Neutrino Masses from Spontaneous Lepton Number Breaking
Cesar Bonilla, Leon M. G. de la Vega, J. M. Lamprea +2
In this paper, we study the viability of having a fermion Dark Matter particle below the TeV mass scale in connection to the neutrino mass generation mechanism. The simplest realiz…
Systematic classification of two loop d = 4 Dirac neutrino mass models and the Diracness-dark matter stability connection
Salvador Centelles Chuliá, Ricardo Cepedello, Eduardo Peinado +1
We provide a complete systematic classification of all two-loop realizations of the dimension four operator for Dirac neutrino masses. Our classification is multi-layered, starting…
Strongly Interacting Neutrino Portal Dark Matter
J. M. Lamprea, E. Peinado, S. Smolenski +1
We present a realistic, simple and natural model of strongly-interacting dark matter based on the neutrino-portal paradigm. The strong interactions at small velocities are generate…
The role of residual symmetries in dark matter stability and the neutrino nature
Cesar Bonilla, Eduardo Peinado, Rahul Srivastava
We consider the class of models where Dirac neutrino masses at one loop and the dark matter stability can be obtained using only the global symmetry already present in…
Scotogenic Dark Symmetry as a residual subgroup of Standard Model Symmetries
Salvador Centelles Chuliá, Ricardo Cepedello, Eduardo Peinado +1
We show that the scotogenic dark symmetry can be obtained as a residual subgroup of the global symmetry already present in Standard Model. We propose a general framewo…
