Connecting Leptogenesis to Observables: From Collider Searches for Right-Handed Neutrinos to Gravitational Waves

Neutrino masses and the baryon asymmetry of the Universe remain two of the most important open questions beyond the Standard Model (SM). Leptogenesis provides an attractive framework that can simultaneously account for both phenomena through the dynamics of heavy right-handed neutrinos. In this talk, I will discuss recent progress in connecting leptogenesis to experimental and observational probes. In particular, I will show how collider searches for right-handed neutrinos and gravitational-wave signals can be used to test and constrain the parameter space relevant for leptogenesis.
