The evolution of multiplicity distribution of a species which undergoes chemical reactions can be described with the help of a master equation. We study the master equation for a fixed temperature, because we want to know how fast different moments of the multiplicity distribution approach their equilibrium value. We particularly look at the 3rd an...

Measured moments of the multiplicity distribution for a given sort of particles are used in the literature for the determination of the phase transition parameters of hot QCD matter in ultrarelativistic heavy-ion collisions. We argue that the subsequent cooling in the hadronic phase, however, may drive the multiplicity distribution out of equilibri...

Evolution of a multiplicity distribution can be described with the help of master equation. We first look at 3rd and 4th factorial moments of multiplicity distributions and derive their equilibrium values. From them central moments and other ratios can be calculated. We study the master equation for a fixed temperature, because we want to know how...

... In a number of presentations by Herold, Nahrgang, Wink, Bluhm, Yin, Ridgway, Sochorova, Tomasik and Rustamo, it was shown how such underlying behaviour might be measured and computed in heavy ion collisions [22], [23], [24], [25], [26], [27], [28] [29], [30]. In particular, one needs to understand for various initial conditions how close does one evolve to a hypothetical critical end point and how does such an evolution affect the extraction of underlying fluctuation measures. ...

... While the overall agreement is good, a slight disagreement with the thermal parameters obtained from fitting the abundances (first order cumulant) has been reported. In [27] it has been pointed out, that this may be a consequence of fast expansion and cooling which drives the particle number distribution out of equilibrium so that its different cumulants cannot be assigned to a unique value of the temperature. ...
