Effective Majorana neutrino decay

Understand

We study the decay of heavy sterile Majorana neutrinos according to the interactions obtained from an effective general theory.

• We describe the two and three-body decays for a wide range of neutrino masses.
• The results obtained and presented in this work could be useful for the study of the production and detection of this particles in a variety of high energy physics experiments and astrophysical observations.
• We show in different figures the dominant branching ratios and the total decay width.
