Description
Light sterile neutrinos remain one of the most intriguing possibilities for physics beyond the Standard Model, motivated by persistent anomalies in short-baseline experiments such as LSND, MiniBooNE, and reactor measurements. In this work, we investigate the sensitivity of the future experiments MOMENT (medium baseline) and DUNE (long baseline) to light sterile neutrinos within the minimal 3+1 framework, highlighting the complementarity of their experimental setups.
We present a comprehensive analysis of active–sterile mixing constraints and, importantly, the CP-violation discovery potential. We derive exclusion limits and demonstrate the critical role of near detectors in significantly strengthening these bounds. Furthermore, we show that sterile neutrinos can impact CP-violation measurements by introducing additional phase degeneracies, particularly in long-baseline, high-energy experiments.
Our results reveal a strong complementarity between DUNE and MOMENT. While DUNE is sensitive to slow sterile oscillations and matter-enhanced effects, MOMENT retains robust sensitivity across a wide range of sterile masses. It is particularly effective at disentangling CP-phase correlations. Together, these experiments can probe regions of sterile-neutrino parameter space that remain weakly constrained by current global data.
