We have analyzed the electron anti-neutrino scattering off electrons and the electron anti-neutrino-nuclei coherent scattering in order to obtain constraints on tensorial couplings. We have studied the formalism of non−standard 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 for the first time electron anti-neutrino-nucleus coherent scattering and its potential to further constrain electron anti-neutrino−quark tensorial couplings is also discussed.

“…In general, neutrino oscillations and NSIs in terrestrial neutrino experiments have been studied extensively in the literature, using the neutrino factory project [14][15][16][17][18][19][20][21] and other different neutrino facilities (like super-beams and β-beams) [22][23][24][25][26] to assess the impact of the NSI effects in neutrino physics.…”

Non-standard interactions using the OPERA experiment

We investigate the implications of non-standard interactions on neutrino oscillations in the OPERA experiment. In particular, we study the non-standard interaction parameter ε μτ . We show that the OPERA experiment has a unique opportunity to reduce the allowed region for this parameter compared with other experiments such as the MI-NOS experiment, mostly due to the higher neutrino energies in the CNGS beam compared to the NuMI beam. We find that OPERA is mainly sensitive to a combination of standard and non-standard parameters and that a resulting anti-resonance effect could suppress the expected number of events. Furthermore, we show that running OPERA for five years each with neutrinos and anti-neutrinos would help in resolving the degeneracy between the standard parameters and ε μτ . This scenario is significantly better than the scenario with a simple doubling of the statistics by running with neutrinos for ten years.

Can R-parity violating supersymmetry be seen in long baseline beta-beam experiments?

2006

Long baseline oscillation experiments may well emerge as test beds for neutrino interactions as are present in R-parity violating supersymmetry. We show that flavour diagonal (FDNC) and flavour changing (FCNC) neutral currents arising therefrom prominently impact a neutrino β-beam experiment with the source at CERN and the detector at the proposed India-based Neutrino Observatory. These interactions may preclude any improvement of the present limit on θ 13 and cloud the hierarchy determination unless the upper bounds on R couplings, particularly λ ′ , become significantly tighter. If R interactions are independently established then from the event rate a lower bound on θ 13 may be set. We show that there is scope to see a clear signal of non-standard FCNC and FDNC interactions, particularly in the inverted hierarchy scenario and also sometimes for the normal hierarchy. In favourable cases, it may be possible to set lower and upper bounds on λ ′ couplings. FCNC and FDNC interactions due to λ type R couplings are unimportant.
