Title: Neutrinoless double beta decay in effective field theory

Abstract: Next-generation neutrinoless double-beta decay (0vbb) experiments
aim to discover lepton number violation in order to shed light on the
nature of neutrino masses. A non-zero signal would have profound
implications by demonstrating the existence of elementary Majorana
particles and possibly pointing towards a solution of matter-antimatter
asymmetry in the universe. However, the interpretation of the
experimental signal (or lack thereof) requires care as complicated
hadronic and nuclear input is required to connect the experimental data
to a fundamental description of lepton-number violation. In this talk, I
use effective field theories to connect 0vbb measurements to the
fundamental lepton-number-violating source. In particular, I will argue
that interpretation in terms of a light Majorana neutrino mass is more
complicated than normally considered.
