The decays "neutrino{heavy} -> neutrino{light} + photon" and "neutrino{heavy} -> neutrino{light} e+ e-" of massive neutrinos

open access: yes, 1999
If, as recently reported by the Super-Kamiokande collaboration, the neutrinos are massive, the heaviest one would not be stable and, though chargeless, could in particular decay into a lighter neutrino and a photon by quantum loop effects. The corresponding rate is computed in the standard model with massive Dirac neutrinos as a function of the ...

Neutrino mixing

open access: yesJournal of Physics G: Nuclear and Particle Physics, 1991
In the first part of these lectures the neutrino mixing hypothesis will be considered in detail. We will discuss the possible schemes of neutrino mixing and present the data of the recent experiments searching for effects due to nonvanishing neutrino masses and mixing angles.In the second part of these lectures the physics of solar neutrinos will be ...

Galaxy Clusters in Dark Matter Window: The Case of the Shapley Supercluster

open access: yesUniverse
Dark matter dominates the matter content of the Universe, yet its particle nature remains elusive. Among the promising multi-messenger astronomy dark matter candidates are weakly interacting massive particles and superheavy dark matter, both of which may

Gravitational Wave Signatures of Warm Dark Matter in the Gauge Extensions of the Standard Model

open access: yesUniverse
We studied the left-right symmetric extension of the standard model (LRSM), featuring a TeV-scale, right-handed (RH) gauge boson WR and three RH neutrinos. This setup naturally realizes the type-II seesaw mechanism for active neutrino masses.
