The formulae for m-order correlators K m of a given particle observable (e.g., energy, transverse momentum or a conserved discrete quantum number) accounting for the track reconstruction efficiencies in a real detector are presented. The calculation of second- to fourth-order correlators is considered in some detail. Similar to the case of an ideal detector, the correlators can be expressed through the event-by-event fluctuation measures of the observable single event mean, the…

Using higher moments of fluctuations and their ratios in the search for the QCD critical point

The QCD critical point can be found in heavy-ion collision experiments via the nonmonotonic behavior of many fluctuation observables as a function of the collision energy. The event-by-event

Incident Energy Dependence of $p_{t}$ Correlations at RHIC

We present results for two-particle transverse momentum correlations, h ∆ p t,i ∆ p t,j i , as a function of event centrality for Au+Au collisions at √ s NN = 20, 62, 130, and 200 GeV at the
