Toward the Discovery of Lepton Creation with Neutrinoless Double-β Decay

by Giovanni Benato (Istituto Nazionale di Fisica Nucleare)

Europe/Rome
Description

The discovery of neutrinoless double-β decay could soon be within reach.
This hypothetical ultra-rare nuclear decay is a portal to new physics beyond the Standard Model.
Its observation would constitute the discovery of a matter-creating process, corroborating leading theories of why the universe contains more matter than antimatter.
It would also prove that neutrinos and anti-neutrinos are not two distinct particles, but can transform into each other, generating their own mass in the process.
The recognition that neutrinos are not massless necessitates an explanation and has boosted interest in neutrinoless double-β decay.
The field is now at a turning point. A new round of experiments is currently being proposed for the next decade to cover an important region of the parameter space.
Advancements in nuclear theory are laying the groundwork to connect the nuclear decay with its underlying mechanisms.
Meanwhile, the particle theory landscape continues to find new motivations for neutrinos to be their own antiparticle.
This review will cover nuclear theory, particle theory, and (mostly) experimental aspects connected to neutrinoless double-β decay,
with the goal of exploring the path toward its discovery.
