Description
Neutrino mass and mixing cannot be explained with the Standard Model which leads to the exploration of frameworks beyond the Standard Model (BSM). The possibility of neutrinos interacting with fermions via a scalar mediator is one of the interesting prospects. These new interactions can modify the neutrino oscillation probabilities leading to observable effects in experiments. The effects of SNSI appear as a matter-dependent correction to the neutrino mass matrix which allows for the exploration of absolute neutrino masses via oscillation experiments. SNSI can also affect the physics sensitivities in long-baseline experiments. We will present our study on the impact of a scalar-mediated NSI on the neutrino mass ordering (MO) sensitivities at long-baseline neutrino experiments, i.e., DUNE and HK. We study the effects on MO sensitivities at these experiments assuming that SNSI parameters are present in nature and are constrained from other non-LBL experiments. The presence of SNSI can affect the mass ordering sensitivities of these experiments. Furthermore, we analyze the potential synergy by combining data from DUNE with HK. This approach allows for a more extensive exploration of the parameter space, potentially uncovering synergistic effects that enhance the MO sensitivities.
