Description
The intriguing possibility of Bose-Einstein condensation of pions (BEC) at the LHC [1-3] is examined with the use of higher order moments of the multiplicity distribution. The scaled variance, skewness and kurtosis are calculated for the pion system in and out of chemical equilibrium. The effects of resonance decays are estimated. The obtained results show the possibility to see a significant increase of the kurtosis for the case of BEC in the measured data.
