Neutrino oscillations beyond the Standard Model in the future beta-beam experiments

Abstract

In the present work we study the possible effects of physics beyond the standard Model in future neutrino oscillation experiments, where these leptons will be produced in beta decays of accelerated radioactive ions — the so-called beta-beam. Therefore, first we set the limits on the parameters describing new scalar, vector and tensor currents. Then, we use the statistical operator to describe the state of antineutrinos produced in the Fermi and Gamow-Teller nuclear beta decays as such state will be mixed in general. Next, we consider the antineutrinos oscillations in the vacuum and their detection through quasielastic scattering on free protons. Finally, we give a numerical estimate of the possible size of the influence of exotic vector currents on the number of detected antineutrinos, produced in helium-6 decays.
