Description
We consider the prospects for detecting right-handed (Standard Model
singlet) neutrinos introduced in the see-saw mechanism at future
accelerators. This requires sufficiently large mixing of these
neutrinos with the left-handed neutrinos, which is only possible if
contributions from different right-handed neutrinos to the light
neutrino mass matrix cancel at a level of $10^{-8}$. We search for
possible symmetries behind this cancellation. Light neutrino masses can
be generated as a result of small perturbations related to violation of
these symmetries. The impact of these perturbations on LHC physics is
however negligible so that the mechanism of neutrino mass generation and
LHC physics are essentially decoupled in general. Under additional
assumptions about symmetry breaking some correlation can appear between
the collider observables and features of the neutrino mass matrix.
