Abstract

We study how much the unique ability of the OPERA experiment to directly detect ντ can 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 νμ to νe transitions we also include the impact of possible Double Chooz data. In all cases we find that the ντ sample of OPERA is too small to be statistically significant, even if one doubles the nominal exposure of OPERA to 9 x1019 pot. OPERA's real benefit for this measurement lies in its very high neutrino energy and hence very different L/E compared to MINOS.
