Abstract

The measurement of event–by–event fluctuations and charge–dependent particle correlations are used to study properties of nuclear matter at high temperatures as produced in ultrarelativistic heavy–ion collisions. We present results for event–by–event net–charge fluctuations and charge balance functions in ∆η and ∆ϕ in Pb–Pb collisions at √ sNN = 2.76 TeV.
