Abstract

In this paper, we present the physics performance of the ESSnuSB experiment in the standard three flavor scenario using the updated neutrino flux calculated specifically for the ESSnuSB configuration and updated migration matrices for the far detector. Taking conservative systematic uncertainties corresponding to a normalization error of for signal and for background, we find that there is CP violation discovery sensitivity for the baseline option of 540 km (360 km) at . The corresponding fraction of for which CP violation can be discovered at more than is . Regarding CP precision measurements, the error associated with is around and with is around for the baseline option of 540 km (360 km). For hierarchy sensitivity, one can have sensitivity for 540 km baseline except and sensitivity for 360 km baseline for all values of . The octant of can be determined at for the values of: ( and ) for baseline of 540 km (360 km). Regarding measurement precision of the atmospheric mixing parameters, the allowed values at are: () and eV eV ( eV eV) for the baseline of 540 km (360 km).
