Abstract
We investigate the potential of the next generation long-baseline neutrino experiments DUNE and T2HK as well as the upcoming reactor experiment JUNO to constrain Non-Standard Interaction (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 to constrain NSI parameters. We present excluded regions in NSI parameter space, $\epsilon_{\alpha \beta}$ assuming Standard Model (SM) as the null hypothesis. We further explore the correlations between the NSI parameters and CP-violation phase.
Highlights
Neutrino oscillations can successfully describe neutrino flavor transitions
We study how well the precise measurements of oscillation probabilities at Deep Underground Neutrino Experiment (DUNE), T2HK and Jiangmen Underground Neutrino Observatory (JUNO) can be used to probe the existence of nonstandard neutrino neutral current interactions and discuss how using the combined data of the upcoming DUNE, T2HK and JUNO experiments can constrain NSI assuming it is consistent with the standard paradigm
We have assumed 7 years of data taking for DUNE experiment, 6 years for JUNO experiment and 10 years for T2HK experiment
Summary
Neutrino oscillations can successfully describe neutrino flavor transitions. In 1978, the matter potential for neutrino propagation through matter was proposed [1]. The exact value of the mixing angle θ13 has been determined to good accuracy by reactor experiments such as Daya Bay [60] and RENO [61] with the previous hint from the combination of KamLAND and solar neutrino observatories data [62]. We study how combining data of future long-baseline experiments DUNE and T2HK with the precise measurements of future reactor experiment JUNO is going to determine the standard oscillation parameters by a higher accuracy. We study how well the precise measurements of oscillation probabilities at DUNE, T2HK and JUNO can be used to probe the existence of nonstandard neutrino neutral current interactions and discuss how using the combined data of the upcoming DUNE, T2HK and JUNO experiments can constrain NSI assuming it is consistent with the standard paradigm.
