Influence of Majorons on Neutrino Oscillations in the Presence of a Magnetic Field and Matter
Abstract
Neutrino spin–flavor oscillations in the magnetic field, matter, and majoron fields are studied. The effective Lagrangian of Majorana neutrino interaction with a majoron field mediated by heavy neutrino is calculated. It is shown that the presence of a majoron field with a high energy density significantly shifts the resonances in neutrino oscillations, or even induces new resonances. The influence of majorons suppresses oscillations for neutrino energies below 10 MeV. Additionally, the dependence of the oscillations probabilities on the Dirac and Majorana $$CP$$ -violating phases becomes weaker under the influence of a dense majoron field. These findings can be applied to experiments that study neutrinos from supernovae, such as JUNO, DUNE, and the upcoming Hyper-Kamiokande experiment.
