The observed pattern of fermion masses and mixing is an outstanding puzzle in particle
physics, generally known as the flavor problem. Over the years, guided by precision neutrino …

The understanding of the physical processes that lead to the origin of matter in the early
Universe, creating both an excess of matter over anti-matter and a dark matter abundance …

Despite numerous dedicated experimental searches, the elusive nature of dark matter [1]
remains one of the most important problems in modern physics. High-energy neutrinos …

In the classic type I seesaw mechanism with very heavy right-handed (RH) neutrinos, it is
possible to account for dark matter via RH neutrino portal couplings to a feebly interacting …

We propose a minimal seesaw extension to simultaneously account for realistic neutrino
mass and mixing, the baryon asymmetry of the Universe via leptogenesis and a viable dark …

We investigate a simple extension of the standard model in which the dark matter consists of
a feebly interacting fermion, charged under a new Z 4 symmetry, that is produced in the early …

A bstract Stringent constraints on the interactions of dark matter with the Standard Model
suggest that dark matter does not take part in gauge interactions. In this regard, the …

We propose a minimal model to simultaneously account for a realistic neutrino spectrum
through a type-I seesaw mechanism and a viable dark matter relic density. The model is an …

Indirect searches for signatures of corpuscular dark matter have been performed using all
cosmic messengers: gamma rays, cosmic rays, and neutrinos. The search for dark matter …

We analyse a model that connects the neutrino sector and the dark sector of the universe via
a mediator $\Phi $, stabilised by a discrete $ Z_4 $ symmetry that breaks to a remnant $ Z_2 …
