Description
Studies associated with neutrinos are now at the center stage of high energy physics search to decipher the signal of physics beyond the standard model. With the next generation neutrino experiments neutrino physics may enter the precision era. However, neutrino oscillations in the matter could get affected by the sub-dominant, yet unknown, non-standard interactions. The long-baseline (LBL) neutrino experiments will be sensitive to these effects and can provide information on the unknown oscillation parameter values. We study the parameter degeneracies that can occur in DUNE, T2HK experiments, and a combination of both due to nonstandard interactions (NSI), arising simultaneously, from two different sectors, i.e., $e-\mu$ and $e-\tau$. Our analysis reveals a significant impact that dual NSIs may have on the sensitivity of atmospheric mixing angle $\theta_{23}$ in the normal ordering (NO) case. Furthermore, when non-standard interaction from the $e-\mu$ and $e-\tau$ sectors are included simultaneously, we see noticeable changes in the probabilities for DUNE, T2HK, as well as on combined analysis involving both. Moreover, the CP sensitivity gets affected significantly due to the presence of dual NSIs, and, in addition, the CP asymmetry also exhibits an appreciable difference which can be tested in the LBL experiments.
