Leptogenesis, Dark Matter and Gravitational Waves from Discrete Symmetry Breaking
Subhaditya Bhattacharya, Niloy Mondal, Rishav Roshan +1
We analyse a model that connects the neutrino sector and the dark sector of the universe via a mediator , stabilised by a discrete symmetry that breaks to a remnant …
Neutrino masses from new seesaw models: Low-scale variants and phenomenological implications
Alessio Giarnetti, Juan Herrero-Garcia, Simone Marciano +2
With just the Standard Model Higgs doublet, there are only three types of seesaw models that generate light Majorana neutrino masses at tree level after electroweak spontaneous sym…
Neutrino masses from new Weinberg-like operators: Phenomenology of TeV scalar multiplets
Alessio Giarnetti, Juan Herrero-Garcia, Simone Marciano +2
The unique dimension- effective operator, , known as the Weinberg operator, generates tiny Majorana masses for neutrinos after electroweak spontaneous symmetry breaking. I…
Asymmetries in Extended Dark Sectors: A Cogenesis Scenario
Juan Herrero-Garcia, Giacomo Landini, Drona Vatsyayan
The observed dark matter relic abundance may be explained by different mechanisms, such as thermal freeze-out/freeze-in, with one or more symmetric/asymmetric components. In this w…
