Abstract

ESSnuSB (the European Spallation neutrino Super Beam) is a design study for a long-baseline neutrino experiment to precisely measure the CP violation in the leptonic sector, at the second neutrino oscillation maximum, using a beam driven by the uniquely powerful ESS linear accelerator. The ESSnuSB CDR showed that after 10 years, about 72% of the possible CP violating phase range will be covered with 5 sigma C.L. to reject the no CP violation hypothesis. The expected precision for the CP violating phase is better than 8 degrees for all allowed values, making it the most precise proposed experiment in the field. The extension project, ESSnuSB+, aims in designing two new facilities, a Low Energy nuSTORM and a Low Energy Monitored Neutrino Beam to use them to precisely measure the neutrino-nucleus cross-section in the energy range of 0.2 to 0.6 GeV. A new water Cherenkov detector will also be designed to measure cross sections and serve to explore the sterile neutrino case.
