Abstract

In this paper we have studied the phenomenon of nonstandard interaction mediated by a scalar field (SNSI) in the context of P2SO experiment and compared its sensitivity with DUNE. In particular, we have studied the capability of these two experiments to put bounds on the diagonal SNSI parameters, i.e., eta ee, eta mu mu, and eta tau tau and studied the impact of these parameters on the determination of neutrino mass ordering, octant of theta 23 and CP violation (CPV). In our analysis we find that, the parameter Delta m231 has a nontrivial role if one wants estimate the bounds on eta mu mu and eta tau tau assuming SNSI does not exist in nature. Our results show that sensitivity of P2SO and DUNE to constraint eta mu mu and eta tau tau are similar whereas the sensitivity of DUNE is slightly better for eta ee. We find that the mass ordering and CPV sensitivities are mostly affected by eta ee compared to eta mu mu and eta tau tau if one assumes SNSI exists in nature. On the other hand, octant sensitivity is mostly affected by eta mu mu and eta tau tau. These sensitivities can be either higher or lower than the standard three flavor scenario depending on the relative sign of the SNSI parameters. Regarding the precision of atmospheric mixing parameters, we find that the precision of theta 23 deteriorates significantly in the presence of eta mu mu and eta tau tau.
