Abstract

The role of β\beta decay as a low-energy probe of physics beyond the Standard Model is reviewed. Traditional searches for deviations from the Standard Model structure of the weak interaction in β\beta decay are discussed in the light of constraints from the LHC and the neutrino mass. Limits on the violation of time-reversal symmetry in β\beta decay are compared to the strong constraints from electric dipole moments. Novel searches for Lorentz symmetry breaking in the weak interaction in β\beta decay are also included, where we discuss the unique sensitivity of β\beta decay to test Lorentz invariance. We end with a roadmap for future β\beta-decay experiments.
