Event selection efficiency with the DAMA/LIBRA’s event selection applied to COSINE-100 data. Event selection efficiencies determined from the \(^{60}\)Co calibration data using the multiple-hit events of the COSINE-100 crystal (crystal 6) (black points) are compared with those of DAMA/LIBRA-phase1 (red points)24 and DAMA/LIBRA-phase2 (blue points)25. Here selection criteria shown in Fig. 1 are determined to provide efficiencies similar to the DAMA/LIBRA-phase2.
