The Majoron is a hypothetical particle that is associated with certain extensions of the Standard Model of particle physics, particularly in the context of theories that involve the violation of lepton number conservation. It is often discussed in relation to the phenomenon of neutrinoless double beta decay, which is a rare process that would provide evidence for the Majorana nature of neutrinos (i.e., neutrinos being their own antiparticles).
