Investigation of the process of radiation of a neutrino pair that allows one to observe the violation of the conservation of L in electronic shells using laser spectroscopy methods.
Features of the flavor neutrino transitions at short macroscopic distances will be investigated. This regime is caused by the offshell behavior of the
neutrino propagator;
it arises in a covariant fieldtheoretical theory of neutrino oscillations and has no analogue in the standard quantummechanical approach. Possible
experimental manifestation
of this unusual regime of the neutrino oscillations will be discussed.
Our work on optimization of the Monte Carlo neutrino generator GENIE ? the most popular tool for modeling and data processing used by essentially
all current accelerator
experiments on neutrino interactions with matter will be continued. The work on the detailed User Guide for the 3.0.0 release of the GENIE package
is planned to be accomplished.
