Optimal configuration of Protvino to ORCA experiment for hierarchy and non-standard interactions
In this paper, we study the hierarchy sensitivity of Protvino to ORCA (P2O) experiment in three flavor scenario as well as its sensitivity to non-standard interactions (NSI) in neutrino propagation. Because of the largest possible baseline length of 2595 km, P2O is expected to have strong sensitivit...

Our results show that for a background reduction factor of 0.46 and appearance channel background systematic normalization error of 4%, the hierarchy sensitivity of P2O becomes equivalent of DUNE for δCP=195o. We call this configuration of P2O as optimized P2O. Regarding the study of NSI, we find that for εeμ (εeτ) sensitivity of DUNE is similar (better) as compared to optimized P2O when both εeμ and εeτ are included in the analysis. Our results show that in presence of NSI, the change of hierarchy sensitivity with respect to the standard three flavor scenario is higher in P2O as compared to DUNE. Further, hierarchy sensitivity in presence of NSI is lower (higher) than sensitivity in the standard three flavor scenario for δCP=270o(90o). It is important to note that the hierarchy sensitivity of optimized P2O does not get significantly better than DUNE for the current favourable values of δCP which is 180o < δCP < 360o as obtained by the global analysis in both standard three flavour and in presence of NSI.
