The Opportunity Offered by the ESSnuSB Project to Exploit the Larger Leptonic CP Violation Signal at the Second Oscillation Maximum and the Requirements of This Project on the ESS Accelerator Complex

Figure 9

Curves showing the dependence of the fraction of values of for which a CP violation discovery at 5 and 3, respectively, can be made as a function of event statistics, or exposure, where the nominal exposure corresponds to 10 years of data taking. (a) is for a proton energy of 2.0 GeV (current ESS design) and (b) for 2.5 GeV. The upper boundaries of the colored bands were obtained assuming the hierarchy to be known (NH) and the lower boundaries assuming the hierarchy to be unknown; that is, it is marginalized over. The systematic errors used to produce these plots are those shown in the right column (SB Opt.) of Table 3 [18].
