Show affiliationsEvent-by-event fluctuations of mean pT and net charge in 40, 80 and 158 A GeV/c Pb+Au collisions are presented. The observed dynamical mean pT fluctuations in central events of about 1% are very similar to results from RHIC. The centrality dependence of mean pT fluctuations at 158 A GeV/c shows a peculiar non-monotonic pattern with respect to the extrapolation from the fluctuations measured in p+p collisions. Dynamical net charge fluctuations smaller than the charge conservation limit are observed. After correction for charge conservation, the measured fluctuation signal in central events is comparable to RHIC results.
