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

Table 3

The different sources of uncertainty that contribute to the total systematic uncertainty in the determination of the CP violating angle . This table is an extraction of information from a table used in [18]. Here, only the uncertainties for the Super Beam cases “SB Def.” (for default) are used to obtain the results shown in Figures 8 and 10 and “SB Opt.” (for optimistic) to obtain the results shown in Figure 9.

Fiducial volume FD	2.5%	1.0%
Flux error signal	7.5%	5%
Flux error background	15%	10%
Flux error signal	15%	10%
Flux error background	30%	20%
Background uncertainty	7.5%	5%
Cross sections × eff. QE	15%	10%
Cross sections × eff. RES	15%	10%
Cross sections × eff. DIS	7.5%	5%
Effec. ratio QE	11%	3.5%
Effec. ratio RES	5.4%	2.7%
Effec. ratio DIS	5.1%	2.5%
