Massive Neutrinos as Intermediaries in Scalar Field Decay

Abstract

Neutrinos are fundamental particles that have unique properties and are difficult to detect because they do not experience electromagnetic interactions. In this study, the models used are the Left-Right Symmetry Model and Extra Scalar Fields. The focus of this study is the analysis of the decay of the scalar field ​ \chi_L in the left sector mediated by the right-handed massive neutrino \nu_R. This decay produces two fermions ( \ell_L and q_L\bar)   and the scalar field \phi_L. The decay rate of this process is proportional to the fifth power of the mass of the scalar field \phi_L and inversely proportional to the fourth power of the neutrino mass \nu_R. The decay results contribute entropy to the left sector, heating the sector and triggering a temperature imbalance between the left and right sectors.
