“…The figures in the bottom panels are consistent with the results from Ref. [15]. From these plots, we see that in the absence of an ND, the CP violation sensitivity in the presence of sterile neutrinos is lower as compared to the case when we include an ND along with an FD.…”

“…Therefore, the conclusion obtained in Ref. [15] that the CP violation sensitivity deteriorates substantially in the presence of sterile neutrinos can be drastically altered if there is an ND. We have checked that for the case of an FD only, the sensitivity is affected due to the marginalization of θ 14 (if θ 14 is fixed, then the value of the χ 2 function becomes very high).…”

“…Apart from that if there is a near detector (ND), then it is also possible to probe the oscillations that are governed by the light sterile neutrino mass-squared differences. Analyses of sterile neutrinos in the context of long-baseline neutrino oscillation experiments have been carried out previously in the literature [6][7][8][9][10][11][12][13][14][15][16][17][18].…”

“…Here we would like to mention that Ref. [15] has discussed (b) assuming an FD only. However, as we mentioned earlier, with an FD only, the oscillations of sterile neutrinos with ∆m 2 41 ∼ 1 eV 2 are averaged out.…”

We present a comprehensive analysis in the 3+1 active-sterile neutrino oscillation scenario for the sensitivity of the ESSnuSB experiment in the presence of light sterile neutrinos assuming both a far (FD) and a near (ND) detector. Our analysis show that when the ND is included, the results are significantly different compared to the ones obtained with the FD only. We find that the capability of ESSnuSB to constrain the sterile mixing parameters is sin 2 2θ µe ∼ 10 −4 for ∆m 2 = 1 eV 2 if the ND is included and it becomes sin 2 2θ µe ∼ 10 −2 without the ND. Furthermore, we show that the sensitivity can go down to sin 2 2θ µe ∼ 10 −3 for the most conservative choice of the systematics on the ND. Comparing the sensitivity with T2HK, T2HKK, and DUNE by considering the FD only, we find that the sensitivity of ESSnuSB is smaller for most of the parameter space. Studying the CP violation sensitivity, we find that if the ND is included, it can be larger in the 3+1 scenario than in the standard one. However, if the ND is not included, the sensitivity is smaller compared to the one in the standard scenario. We also find that the CP violation sensitivity due to δ 13 is larger compared to the one induced by δ 24 . The sensitivities are slightly better for the dominant neutrino running ratio of ESSnuSB.

Several anomalies observed in short-baseline neutrino experiments suggest the existence of new light sterile neutrino species. In this review, we describe the potential role of long-baseline experiments in the searches of sterile neutrino properties and, in particular, the new CP-violation phases that appear in the enlarged 3 + 1 scheme. We also assess the impact of light sterile states on the discovery potential of long-baseline experiments of important targets such as the standard 3-flavor CP violation, the neutrino mass hierarchy, and the octant of θ 23 .We also mention the work [26], where the combination of MINOS, Daya-Bay, and Bugey-3 was considered.

Next generation neutrino oscillation experiments are expected to measure the remaining oscillation parameters with very good precision. They will have unprecedented capabilities to search for new physics that modify oscillations. DUNE, with its broad band beam, good particle identification, and relatively high energies will provide an excellent environment to search for new physics. If deviations from the standard three-flavor oscillation picture are seen however, it is crucial to know which new physics scenario is found so that it can be verified elsewhere and theoretically understood. We investigate several benchmark new physics scenarios by looking at existing long-baseline accelerator neutrino data from NOvA and T2K and determine at what sensitivity DUNE can differentiate among them. We consider sterile neutrinos and both vector and scalar non-standard neutrino interactions, all with new complex phases, the latter of which could conceivably provide absolute neutrino mass scale information. We find that, in many interesting cases, DUNE will have good model discrimination. We also perform a new fit to NOvA and T2K data with scalar NSI.
