A combined study of source, detector and matter non-standard neutrino interactions at DUNE

We simultaneously investigate source, detector and matter non-standard neutrino interactions at the proposed dune experiment. our analysis is performed using a markov chain monte carlo exploring the full parameter space. we find that the sensitivity of dune to the standard oscillation parameters is worsened due to the presence of non-standard neutrino interactions. in particular, there are degenerate solutions in the leptonic mixing angle θ 23 and the dirac cp-violating phase δ. we also compute the expected sensitivities at dune to the non-standard interaction parameters. we find that the sensitivities to the matter non-standard interaction parameters are substantially stronger than the current bounds (up to a factor of about 15). furthermore, we discuss correlations between the source/detector and matter non-standard interaction parameters and find a degenerate solution in θ 23. finally, we explore the effect of statistics on our results.
