Event-by-event efficiency fluctuations and efficiency correction for cumulants of superposed multiplicity distributions in relativistic heavy-ion collision experiments
We performed systematic studies on the effects of event-by-event efficiency fluctuations on efficiency correction for cumulant analysis in relativistic heavy-ion collision experiments.Experimentally, particle efficiencies of events measured under different experimental conditions should be different.For fluctuation measurements, the final event-by-event multiplicity distributions should be the superposed distributions of various type of …
