Description
The reference design of the near detector for the LBNE/F experiment is a high-resolution Fine-Grained Tracker (FGT) capable of precisely measuring all four species of neutrinos: νμ, νe, ν ̄μ and ν ̄e. The goal of the FGT is to constrain the systematic errors, below the corresponding statistical error in the far detector, for all oscillation studies; and to conduct a wide range of precision measurements and searches in neutrino physics. We present sensitivity studies of the measurements – critical to constraining the systematics in oscillation searches – of the absolute and relative neutrino flux using the various techniques: (1) neutrino electron neutral current scattering (CC), (2) neutrino electron charge-current scattering (CC), (3) ν ̄μ proton QE scattering, (4) Coherent ρ production for absolute flux and (4) Low-ν method for relative flux.
Historically, the limited knowledge of the (anti)-neutrino fluxes has been the dominant systematic uncertainty for past neutrino scattering experiments. The precision in the determination of the absolute and relative fluxes achieved in DUNE-ND will allow for the first time to fully exploit the potential of the (anti)-neutrino probe.
