Studying the physics potential of long-baseline experiments in terms of new sensitivity parameters

Abstract

We investigate physics opportunities to constraint the leptonic CP-violation phase δCP through numerical analysis of working neutrino oscillation probability parameters, in the context of long-baseline experiments. Numerical analysis of two parameters, the “transition probability δCP phase sensitivity parameter (⁠AM⁠)” and the “CP-violation probability δCP phase sensitivity parameter (⁠ACP⁠),” as functions of beam energy and/or baseline have been carried out. It is an elegant technique to broadly analyze different experiments to constrain the δCP phase and also to investigate the mass hierarchy in the leptonic sector. Positive and negative values of the parameter ACP⁠, corresponding to either hierarchy in the specific beam energy ranges, could be a very promising way to explore the mass hierarchy and δCP phase. The keys to more robust bounds on the δCP phase are improvements of the involved detection techniques to explore lower energies and relatively long baseline regions with better experimental accuracy.
