The gamma/hadron discriminator LCm in realistic air shower array experiments

Abstract

Abstract In this article, it is shown that the $$C_k$$ C k and LCm variables, recently introduced as an effective way to discriminate gamma and proton-induced showers in large wide-field gamma-ray observatories, can be generalised to be used in arrays of different detectors and variable fill factors. In particular, the $$C_k$$ C k profile discrimination capabilities are evaluated for scintillator and water Cherenkov detector arrays.
