Query: Neutrino mixing in the $\mu\nu$SSM   Recently, several reactor oscillation experiments have successively measured
a nonzero value for the neutrino mixing angle ${\theta_{13}}$, which is greater
than 5 standard deviations. Within framework of the $\mu$ from $\nu$
Supersymmetric Standard Model ($\mu\nu$SSM), three tiny neutrino masses are
generated at the tree level through TeV scale seesaw mechanism. In this work,
we analyze the neutrino masses and mixing in the $\mu\nu$SSM with a "top down"
method, assuming neutrino mass spectrum with normal ordering (NO) or inverted
ordering (IO).
