Description

Fluctuations of the proton number are measured in ulrarelativistic heavy-ion collisions as a proxy for the fluctuations of the number of baryons. In grand-canonical ensemble, the moments of the baryon number distribution are related to the derivatives of the logarithm of the partition function. In realistic situation corresponding to the measurements, the fluctuations are also determined by the conservation of the baryon number and a limited acceptance of the detector. In this work we study the influence of the rapidity distribution of the net baryons on the observed moments of the proton number distribution, as functions of the width and position of the rapidity window for different collision energies.
