Efficiency corrections for mutually inclusive variables and particle identification effect for mixed-cumulants in heavy-ion collisions

Understand

Mix-cumulants of conserved charge distributions are sensitive observables for probing properties of the QCD medium and phase transition in heavy-ion collisions.

• To perform precise measurements, efficiency correction is one of the most important step.
• In this study, using the binomial efficiency model, we derive efficiency correction formulas for mutually exclusive and inclusive variables.
• The UrQMD model is applied to verify the validity of these formulas for different types of correlations.
