Which long-baseline neutrino experiments are preferable?

Abstract: We discuss the physics of superbeam upgrades, where we focus on T2KK, a NuMI beam line based experiment NOνA*, and a wide band beam (WBB) experiment independent of the NuMI beam line. For T2KK, we find that the Japan-Korea baseline helps resolve parameter degeneracies, but the improvement due to correlated systematics between the two detectors (using identical detectors) is only moderate. For an upgrade of NOνA with a liquid argon detector, we demonstrate that the Ash River site is preferred compared to altern… Show more

“…In both cases, due to the different off-axis angles, the second detector will be predominantly sensitive to the 2 nd maximum. A superficial comparison of the obtainable sensitivities indicates a similar physics performance, where most of the differences is attributable to the different overall exposure [42]. In order to allow for a direct comparison with the results derived in this paper, we refrain from comparing these setups in detail and study instead the effects of the addition of a second baseline to the setup we have introduced in section III A.…”

“…For the case of LAr, only much less detailed and accurate simulations are available since no large LAr detector has ever been operated. The LAr description is based on references [41,42]. We include the ν e andν e appearance channels, with backgrounds from the intrinsic ν e /ν e contamination of the beam, misidentified muons, and neutral current events.…”

“…The resulting 'toolbox' of algorithms will be used to validate the performance assumptions for LAr detectors in common use for neutrino oscillation physics studies (see e.g. [180,371]). These tools will also be useful in estimating reliably the feasibility of non magnetic field solutions to ν −ν separation in the golden channel discussed above; and • Roadmaps: The R&D programmes in Europe and Japan for future large-scale LAr detectors are closely coordinated.…”
