We review the potential to probe new physics with neutrinoless double beta decay (A,Z)→ (A,Z+2)+2e⁻. Both the standard long-range light neutrino mechanism as well as non-standard long-range and short-range mechanisms mediated by heavy particles are discussed. We also stress aspects of the connection to lepton number violation at colliders and the implications for baryogenesis.
