LBNF Neutrino Beam Focusing Uncertainties on DUNE and DUNEPRISM Neutrino Fluxes

Poster Accelerator neutrinos Poster


DUNE is a next generation long baseline neutrino experiment which will study the LBNF neutrino beam at FNAL. Precision measurements of neutrino oscillation parameters with DUNE require estimates of neutrino flux uncertainties. While the dominant uncertainties come from hadron production, uncertainties due to the engineering tolerances for the elements in the LBNF beamline used to focus the beam (so-called focusing effects) are also significant. Some of these elements include the engineering of the magnetic focusing horns, the geometry of the decay pipe, and the horn currents. In this poster, the results of Monte Carlo studies for the expansive suite of beam-focusing uncertainties will be presented. Many of these studies are novel attempts to capture multiple possible focusing effects that have never been considered before. These studies have been performed on the beamline design established in late 2021, which is the standard design for years to come. Additionally, this poster will showcase the effect of the focusing uncertainties for off-axis positions of DUNE-PRISM. DUNE-PRISM studied and reported only ten of the sixty focusing uncertainties in the DUNE 2021 TDR. Off-axis results for the remaining focusing uncertainties are presented here. These flux uncertainties will be used as input into the DUNE-PRISM analyses.
