Low-scale seesaw with flavour and CP symmetries $\unicode{x2013}$ from colliders to leptogenesis
Marco Drewes, Yannis Georis, Claudia Hagedorn +1
We consider an extension of the Standard Model with three right-handed neutrinos, endowed with a flavour symmetry , or , , and CP.…
Towards a precision calculation of in the Standard Model IV: Estimating the impact of positronium formation
Tobias Binder, Marco Drewes, Yannis Georis +3
We present a first assessment of how the previously unexplored effect of positronium formation can impact on the value of the effective number of neutrino species in the Standard M…
On the collider-testability of the type-I seesaw model with 3 right-handed neutrinos
Marco Drewes, Yannis Georis, Juraj Klarić +1
If any heavy neutral leptons are discovered in accelerator-based experiments, key questions will involve their possible connection to neutrino masses or leptogenesis. Working in a…
Confronting the low-scale seesaw and leptogenesis with neutrinoless double beta decay
J. de Vries, M. Drewes, Y. Georis +2
We revisit the impact of heavy neutrinos with masses in the MeV-GeV range on neutrinoless double beta decay () in view of updated results for the lifetime of this process. Wo…
Towards a precision calculation of in the Standard Model III: Improved estimate of NLO contributions to the collision integral
Marco Drewes, Yannis Georis, Michael Klasen +2
We compute the dominant QED correction to the neutrino-electron interaction rate in the vicinity of neutrino decoupling in the early universe, and estimate its impact on the effect…
Recent developments in testable leptogenesis
Yannis Georis
Low-scale leptogenesis is an attractive explanation for the observed baryon asymmetry of our universe that can be tested at a variety of laboratory experiments. In these proceeding…
