Improved Joint FHC + RHC Sterile Analysis with Nu-on-E Scattering Sample

The NOvA experiment measures neutrino oscillations in a nearly pure muon neutrino beam. We use both the neutral current (NC) and the ν_μ charged current (CC) interaction disappearance to search for active-to-sterile neutrino oscillations. NOvA consists of two functionally identical detectors placed 14 mrad off axis of the Fermilab’s NuMI beam line. The Near Detector (ND) is located 100 m underground on-site at Fermilab meanwhile the Far Detector (FD) sits on the surface 810 km away at Ash River, Minnesota. NOvA uses Fermilab’s NuMI beam line which is capable of running in forward or reverse horn current modes, which creates a neutrino or antineutrino beam, respectively. Since our current analysis is limited in systematic uncertainty, we find other ways to constrain our uncertainties. One of which is including the nu-on-e scattering in the dual baseline sterile analysis. This interaction is subject to minimal cross-section uncertainties, which will help to reduce degeneracies between other uncertainty categories. In this talk, we will show how the nu-on-e sample influence the NOvA sterile search sensitivity parameter spaces jointly with FHC and RHC samples.
