Anar Rustamov (National Nuclear Research Center (AZ))


We develop, within a canonical formulation of statistical mechanics, a systematic procedure to evaluate fluctuations of conserved quantities, such as baryon number, measured within an experimental acceptance. In nearly all experiments the baryon number fluctuations are approximated by the corresponding signals for net-proton measurements. We will discuss the validity and, in particular, the energy dependence of this approximation and provide quantitative estimates of differences between net-baryon number and net-proton fluctuations. Finally, we will compare our results up to the 4th cumulants with the corresponding measurements from the STAR and ALICE experiments.
