Sebastian Urrutia-Quiroga - UMass Amherst - TeV-scale lepton number violation: 0νββ-decay, the origin of matter, and energy frontier probes


Lepton number violation (LNV) is a very attractive research topic for theoretical and experimental physicists due to its implications beyond the Standard Model. It provides feasible theoretical explanations to several open questions in particle physics (e.g., the origin of neutrino mass) and also has a rich phenomenology at different energy scales. We explore the underlying connections between neutrinoless double 𝛽−decay (0𝜈𝛽𝛽) experiments, hadron colliders, and cosmology observations. In the context of simplified models, we show that future collider and 0𝜈𝛽𝛽 experimental results may complement each other.
