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

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