Abstract. We
discuss effects of new physics (NP) in neutrino
oscillation experiments. Such
effects can modify
a production
neutrino flux, a detection
cross-section and a matter transition. As
a result, the NP effects change
neutrino oscillations both in vacuum
and in matter. A relation between
the small effects of NP and the
oscillation parameters is
discussed. It is shown for which parameters
the NP effects are suppressed and
when they are potentially large.
Oscillations of non-unitary mixed neutrinos are presented in
more
details.
Keywords. Neutrino
oscillations; non-standard physics.
