Identity method to study chemical fluctuations in relativistic heavy-ion collisions

Marek Gaździcki , Katarzyna Grebieszkow , Maja Maćkowiak-Pawłowska , Stanisław Mrówczyński


Event-by-event fluctuations of the chemical composition of the hadronic final state of relativistic heavy-ion collisions carry valuable information on the properties of strongly interacting matter produced in the collisions. However, in experiments incomplete particle identification distorts the observed fluctuation signals. The effect is quantitatively studied and a new technique for measuring chemical fluctuations, the identity method, is proposed. The method fully eliminates the effect of incomplete particle identification. The application of the identity method to experimental data is explained. © 2011 American Physical Society.
