Neutrino Oscillation Caused by Local Symmetry Broken
Xiao-Yan Wang, Xiang-Jun Chen
TL;DR
This paper proposes a model where neutrino oscillations are caused by local symmetry breaking in the right-handed neutrino sector, extending the Standard Model with large Majorana masses.
Contribution
It introduces a novel extension of the Standard Model that links neutrino oscillations to local symmetry breaking in the right-handed neutrino sector.
Findings
Neutrino flavor conversion can be explained by symmetry breaking.
The model incorporates large Majorana masses for right-handed neutrinos.
It offers a new perspective on the origin of neutrino oscillations.
Abstract
Neutrino flavor conversion is assumed to be induced by right-handed neutrino flavor conversion via seesaw mechanism. Neutrino oscillation is the macroscopic phenomenon before all neutrino flavor-flip interactions reaching equilibrium. The model for the hypothesis is the extension by introducing large mass Majorana right-handed neutrino into the Standard Model and exerting horizontal symmetry only on the right-handed neutrino sector.
