L–E_μ and the LENF
by P. Ballett and S. Pascoli

Here are some supplementary graphs showing the performance of the LENF, with optimistic magnetized detectors, as its baseline distance and stored muon energy are scaled up to those of the HENF.

Here we provide our simulated sensitivities using two different estimates of the number of useful muon decays per year per polarity. The first value 1.0×10²¹ corresponds to the standard IDS-NF configuration of the Neutrino Factory. The higher value of 1.4×10²¹ is based on a potential re-optimisation of the muon accelerator facility.
We have computed the discovery contour plots for each individual choice of baseline and stored muon energy. These were condensed into the files above by using the concept of the discovery fraction. However, the contours themselves can be instructive (for example if the explicit dependence on δ is important) and can be downloaded below.
Non-zero θ₁₃ Discovery Contours
In each of these plots, the contours mark the regions of parameter space for which we can rule out θ₁₃=0 at 3σ significance. For each detector, contours are available for both 1.0×10²¹ muon decays per year per polarity and the optimised value of 1.4×10²¹. Each file contains the contours for the full range of stored muon energies.
CP-Violation Discovery Contours
In these plots, the contours mark the regions of parameter space for which all of the CP-conserving values of δ can be excluded at 3σ significance. As before, for each detector contours have been calculated for both the conventional and optimised estimates of the number of muon decays per year per polarity. Each file contains the contours for the full range of stored muon energies.
Hierarchy Determination Contours
In these plots, the contours mark the regions of parameter space for which the incorrect hierarchy can be ruled out to 3σ significance. As before, for each detector contours have been calculated for both the conventional and optimised estimates of the number of muon decays per year per polarity. Each file contains the contours for the full range of stored muon energies.
