Detectors are a core part of any experiment and they heavily influence what physical phenomena are possible to be observed. Work package 5 (WP5) will use results of the previous ESSnuSB design study, such as the design of the Water Cherenkov Far Detectors, Water Cherenkov Near Detector, Super Fine-Grained Scintillator Detector (SFGD), and emulsion-based detector (νiking), to study the detector performance with respect to non-beam related physics, such as atmospheric neutrinos and supernova neutrinos in addition to the neutrino oscillation physics. WP5 will improve on the existing detector design by studying the effects of gadolinium doping of the water Cherenkov detectors as well. Application of machine learning methods will be also considered in order to improve the event analysis and reconstruction in ESSnuSB+ detectors.
Furthermore, WP5 will design a new detector (Lemon-D) that will observe neutrinos both from the low energy monitored beam (LMNB) and low energy nuSTORM ring (LEnuSTORM). Together with the Near Water Cherenkov, SFGD and νiking it will be used to measure the neutrino interaction cross-section in the energy region of ESSnuSB.
Estimation of the physics reach, i.e. study of the sensitivity of the experimental setup to different physics scenarios, is a key part of any experiment proposal. Therefore, WP5 will study the physics capabilities of the entire ESSnuSB+ setup with inputs from other work packages. It will determine the sensitivity of ESSnuSB+ to non-beam related physics, such as the atmospheric and supernova neutrino physics. Additionally, the possibility of sterile neutrino searches using LEnuSTORM/LEMND neutrino beams observed by the newly envisioned Lemon-D and the ESSnuSB near detectors will be studied.
