Description
The independent participant model is generalized for skewness and kurtosis. The obtained relations allow to calculate the fluctuations of an arbitrarily high order. From the comparison with the SPS and the LHC data it is found that the participants are not nucleons. The contribution of the participant fluctuations increases with the order of fluctuations. The bin width correction procedure used for the analysis of fluctuations at the RHIC and the LHC by STAR and ALICE may not cancel participant fluctuations. Another method to quantify the value of participant number fluctuations experimentally is proposed.
