Effective Majorana neutrino decay

Autor(es):: Duarte, Lucía ; Romero, Ismael ; Peressutti, Javier ; Sampayo, Oscar A.

Resumen:: We study the decay of heavy sterile Majorana neutrinos according to the interactions obtained from an effective general theory. We describe the two- and threebody 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 these 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.
