“…We follow the procedure of Ref. [37], and simulate the DUNE and T2HK data assuming the normal neutrino mass hierarchy, the neutrino CP phase δ = 0, and αα = 0. We scan over both the mass hierarchies, the neutrino oscillation parameters and take only one diagonal αα to be nonzero at a time.…”

We study how nonstandard neutrino interactions (NSI) may be probed by a combination of coherent elastic neutrino-nucleus scattering, neutrino oscillation and collider data, from COHERENT, DUNE, T2HK and the high-luminosity (HL) LHC. We focus on NSI induced by a new flavored gauge boson Z in a generic anomaly-free ultraviolet-complete model. For Z masses above 10 GeV, the HL-LHC has the best sensitivity regardless of the flavor structure of the model. For masses between 0.01 GeV−10 GeV, current LHCb data and future COHERENT data have the best sensitivity unless the Z couplings to the first and second generation leptons are suppressed, in which case DUNE and T2HK have the best sensitivity. For Z masses between about 5 MeV−20 MeV, DUNE and T2HK have the best sensitivity. We also show how joint analyses of COHERENT and LHC data may constrain such models.

“…The proposed long-baseline neutrino experiment using the Hyper-Kamiokande detector and a powerful neutrino beam from the J-PARC proton synchrotron (commonly known as T2HK experiment) is one of the major candidates in the future neutrino road-map to attain the discovery for the above mentioned issues [33][34][35][36][37][38][39][40][41][42]. This superbeam facility heavily relies on the data from both ν µ → ν e andν µ →ν e channels to measure CP-violation 3 (CPV).…”

Neutrino mass hierarchy, CP-violation, and octant of θ 23 are the fundamental unknowns in neutrino oscillations. In order to address all these three unknowns, we study the physics reach of a setup, where we replace the antineutrino run of T2HK with antineutrinos from muon decay at rest (µ-DAR). This approach has the advantages of having higher statistics in both neutrino and antineutrino modes, and lower beam-on backgrounds for antineutrino run with reduced systematics. We find that a hybrid setup consisting of T2HK (ν) and µ-DAR (ν) in conjunction with full exposure from T2K and NOνA can resolve the issue of mass hierarchy at greater than 3σ C.L. irrespective of the choices of hierarchy, δ CP , and θ 23 . This hybrid setup can also establish the CP-violation at 5σ C.L. for ∼ 55% choices of δ CP , whereas the same for conventional T2HK (ν +ν) setup along with T2K and NOνA is around 30%. As far as the octant of θ 23 is concerned, this hybrid setup can exclude the wrong octant at 5σ C.L. if θ 23 is at least 3 • away from maximal mixing for any δ CP .

“…Indeed, the sensitivity to NSI in the DUNE far detector has already been discussed in Refs. [46][47][48][49]. Here we stress that such interactions also lead to an effective nonunitarity-like zero-distance effect, ideal to be probed at a near detector.…”

Exploring the potential of short-baseline physics at Fermilab

We study the capabilities of the short-baseline neutrino program at Fermilab to probe the unitarity of the lepton mixing matrix. We find the sensitivity to be slightly better than the current one. Motivated by the future DUNE experiment, we have also analyzed the potential of an extra liquid Argon near detector in the LBNF beamline. Adding such a near detector to the DUNE setup will substantially improve the current sensitivity on nonunitarity. This would help to remove CP degeneracies due to the new complex phase present in the neutrino mixing matrix. We also study the sensitivity of our proposed setup to light sterile neutrinos for various configurations.
