Mayoron

Majoron is a hypothetical electrically neutral, spinless particle with zero or very small mass. It interacts with a neutrino of the Majorana type and is very weak with all other elementary particles. The existence of a majoron is predicted as a possible consequence of a violation of the law of conservation of lepton charge. In this case, the majoron is the Goldstone boson , arising from spontaneous symmetry breaking, which ensures the conservation of the lepton charge. Due to the presence of mayoron, an additional marjoram mass appears in the neutrino ^{[3] [4]} , due to which it becomes possible to convert neutrinos into antineutrinos. The neutrino itself, in the case where the difference between the particle and the antiparticle is only in helicity , is called the Majorana neutrino . Another consequence of the nonconservation of lepton charge is neutrinoless double beta decay ^[5] .
