Abstract
MuOn-decay MEdium baseline NeuTrino beam experiment (MOMENT) is a next-generation accelerator neutrino experiment looking for more physics study. We try to simulate neutrino oscillations confronting with Charged-Current\&Non-Standard neutrino Interactions(CC-NSIs) at MOMENT. These NSIs could alter neutrino production and detection processes and get involved in neutrino oscillation channels. We separate a perturbative discussion of oscillation channels at near and far detectors, and analyze parameter correlations with the impact of CC-NSIs. Taking $\delta_{cp}$ and $\theta_{23}$ as an example, we find that CC-NSIs can induce bias in precision measurements of standard oscillation parameters. In addition, a combination of near and far detectors using Gd-doped water cherenkov technology at MOMENT is able to provide good constraints of CC-NSIs happening at the neutrino production and detection processes.
Highlights
In the past decades, we have seen enormous progress from neutrino oscillation experiments using solar, atmospheric, accelerator, and reactor neutrinos [1,2,3,4,5,6,7,8]
The charged-current and nonstandard neutrino interactions (CC-NSIs) imposed on the production and detection are two different types: the NSIs involved in the muon decay production process are related to charged leptons, while the NSIs involved in the detection process are associated with quarks
The second term corresponds to the contribution to χ2 from the external inputs which are based on results from previous experiments. σρα is the external error in GLoBES imposed on the central values
Summary
We have seen enormous progress from neutrino oscillation experiments using solar, atmospheric, accelerator, and reactor neutrinos [1,2,3,4,5,6,7,8]. It is promising for us to develop better neutrino detectors to search for subleading NSIs in the current and next-generation neutrino oscillation experiments as a complement to the new physics search with the high intensity machine at the collider. The new detection technology might lead to a discovery of the CP violating phase in the framework of three-flavor neutrino oscillations [55], which complement the study at T2K and NOνA to solve the degeneracy problem and exclude the CP conserved phase at a relatively high confidence level. We focus on the precision measurement of standard neutrino mixing parameters and constraints of NSI parameters in the presence of nonstandard charged-current interactions at the source and detector.
