Sensitivities of future reactor and long-baseline neutrino experiments to NSI

We investigate the potential of future data from next generation long-baseline neutrino experiments, DUNE and T2HK and the upcoming reactor experiment JUNO in constraining neutral current nonstandard neutrino interactions (NSI) parameters. JUNO is going to provide the most precise measurements of solar neutrino oscillation parameters as well as determining the neutrino mass ordering. We study how the results of JUNO combined with those of long-baseline neutrino experiments such as DUNE and T2HK can help to determine oscillation parameters and constrain NSI parameters. We present excluded regions in NSI parameter space, ε_αβ assuming Standard Model (SM) as the null hypothesis. We further explore the correlations between the NSI parameters and the $CP$-violation phase.
