Neutrino Physics and Spontaneous CP Violation in the $\mu \nu$SSM

Abstract

The $\mu \nu$SSM provides a solution to the $\mu$ problem of the MSSM and explains the origin of neutrino masses by simply using right-handed neutrino superfields. We have completed the analysis of the vacua in this model, studying the possibility of spontaneous CP violation through complex Higgs and sneutrino vacuum expectation values. As a consequence of this process, a complex MNS matrix can be present. Besides, we have discussed the neutrino physics and the associated electroweak seesaw mechanism in the $\mu \nu$SSM, including also phases. Current data on neutrino masses and mixing angles can easily be reproduced.
