Radiative Majorana Neutrino Masses
We present new radiative mechanisms for generating Majorana neutrino masses, within an extension of the standard model that successfully generates radiative charged lepton masses, order by order, from heavy sequential leptons. Only the new sequential neutral lepton has a right-handed partner, and its Majorana mass provides the seed for Majorana neutrino mass generation. Saturating the cosmolog-...
متن کاملRunning of Radiative Neutrino Masses: The Scotogenic Model
We study the renormalization group equations of Ma’s scotogenic model, which generates an active neutrino mass at 1-loop level. In addition to other benefits, the main advantage of the mechanism exploited in this model is to lead to a natural loopsuppression of the neutrino mass, and therefore to an explanation for its smallness. However, since the structure of the neutrino mass matrix is alter...
متن کاملSupersymmetric Model of Radiative Seesaw Majorana Neutrino Masses
The radiative seesaw mechanism proposed recently is minimally extended to include supersymmetry in a specific model. Relevant related issues such as leptogenesis and dark matter are discussed. If the standard model (SM) of particle interactions is extended to include three heavy neutral singlet Majorana fermions Ni (i = 1, 2, 3) and a second scalar doublet η = (η , η) with zero vacuum expectati...
متن کاملRadiative Neutrino Masses in a SUSY GUT Model
Radiatively-induced neutrino mass matrix is investigated within the framework of an SU(5) SUSY GUT model. The model has matter fields of three families 5L(+)i +5L(+)i in addition to the ordinary matter fields 5L(−)i +10L(+)i and Higgs fields H(+)+H(0), where (+, 0,−) denote the transformation properties (ω, ω, ω) (ω = +1) under a discrete symmetry Z3. R-parity violating terms are given by 5L(+)...
متن کاملGauged B − 3Lτ and Radiative Neutrino Masses
If the minimal standard model of quarks and leptons is extended to include just a righthanded partner to ντ , then the quantum number B − 3Lτ can be added as a gauge symmetry without the appearance of anomalies. A suitable extension of the scalar sector allows one neutrino to have a seesaw mass, and the other two to have radiative masses, with acceptable phenomenological values for neutrino osc...
