TENSORIAL NSI AND UNPARTICLE PHYSICS IN NEUTRINO SCATTERING
/ Authors
/ Abstract
We have analyzed the electron antineutrino scattering off electrons and the electron antineutrino–nuclei coherent scattering in order to obtain constraints on tensorial couplings. We have studied the formalism of nonstandard interactions (NSI) as well as the case of unparticle physics. For our analysis we have focused on the recent TEXONO collaboration results and we have obtained current constraints to possible electron antineutrino–electron tensorial couplings in both new physics formalisms. The possibility of measuring electron antineutrino–nucleus coherent scattering for the first time and its potential to further constrain electron antineutrino–quark tensorial couplings is also discussed.
