Can OPERA help in constraining neutrino non-standard interactions?

Abstract

We study how much the unique ability of the OPERA experiment to directly detect ν_τcan help in probing new, non-standard contact interactions of the third family of neutrinos. We perform a combined analysis of future, high-statistics MINOS and OPERA data. For the case of non-standard interactions in ν_μto ν_e transitions we also include the impact of possible DoubleCHOOZ data. In all cases we find that the ν_τsample of OPERA is too small to be statistically significant, even if one doubles the nominal exposure of OPERA to 4.5E20 pot. OPERA's real benefit for this measurement lies in its very high neutrino energy and hence very different L/E compared to MINOS.
