Neutrino masses and mixing in $\mu\nu$SSM

Understand

$\mu\nu$SSM is an $R$-parity violating non-minimal supersymmetric model which uses right chiral neutrino superfields to solve the $\mu$-problem.

• The $R$-parity violation together with a TeV scale seesaw mechanism using right handed neutrinos are instrumental for the light neutrino mass generation in $\mu\nu$SSM.
• We show that it is possible to accommodate three flavour global neutrino data in $\mu\nu$SSM with three massive neutrinos at the tree level.
• Ingression of the one-loop corrections to neutrino masses and mixing shows certain variations over the tree level analysis depending on the specific hierarchy of neutrino masses involved.
