Optimal configuration of Protvino to ORCA experiment for hierarchy and non-standard interactions
Abstract In this paper, we study the hierarchy sensitivity of Protvino to ORCA (P2O) experiment in three flavour 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...

It is important to note that hierarchy sensitivity of optimized P2O does not get significantly better than DUNE for the current favourable values of δ CP which is 180° < δ CP < 360° as obtained by the global analysis in both standard three flavour and in presence of NSI.
