Multi-component Dark Matter in a Novel Three-Loop Inverse Scotogenic Seesaw Model
Asmaa Abada, Nicolás Bernal, A. E. Cárcamo Hernández +4
We consider a model which provides an explanation of the origin of light neutrino masses, the baryon asymmetry of the Universe -- via leptogenesis -- and explains the observed dark…
Challenging Majorana neutrino effects in and decays
Asmaa Abada, Claire Chevallier, Luighi P. S. Leal +3
The paper examines how lepton-number-violating effective operators influence the rare decays B→K^{(*)}νν and K→πνν, showing that standard SMEFT operators are tightly constrained by…
Dynamical scotogenic generation of the Linear and Inverse seesaws
Asmaa Abada, Antonio Enrique Cárcamo Hernández, Salvador Urrea
We propose an economical model in which the tiny active neutrino masses arise from an interplay of linear and inverse seesaw mechanisms. The Standard Model is extended by a local $…
Investigating DUNE oscillations sensitivity to sterile Pseudo-Dirac Neutrinos
Asmaa Abada, João Paulo Pinheiro, Salvador Urrea
We explore the sensitivity of the Deep Underground Neutrino Experiment (DUNE) to sterile neutrino oscillations within a (pseudo-Dirac pair) framework. We first consider a pair…
Testable dark matter solution within the seesaw mechanism
A. Abada, G. Arcadi, M. Lucente +1
The presence of a dark matter component in the Universe, together with the discovery of neutrino masses from the observation of the oscillation phenomenon, represents one of the mo…
