Abstract

In the era of precision neutrino physics, we study the influence of nonstandard interactions (NSI) of matter on the question of neutrino mass ordering and its resolution. At long-baseline experiments, since matter effects play a crucial role in addressing this very important question, it is timely to investigate how subleading effects due to NSI may affect and drastically alter inferences pertaining to this question. We demonstrate that the sensitivity to mass ordering gets significantly impacted due to NSI effects for various long-baseline experiments, including the upcoming long-baseline experiment Deep Underground Neutrino Experiment (DUNE). Finally, we draw a comparison between DUNE and the sensitivities offered by two of the current neutrino beam experiments, NOvA and T2K.
