“…NA49 and NA61 did not find any possible signatures of CP when studying the energy dependence (Pb + Pb and also p + p collisions) of chemical (particle type) fluctuations [51,53,64,65]. Also, electric charge [66] and azimuthal angle [64] fluctuations in central Pb+Pb data did not show any unexpected behaviour. The RHIC BES studied: netcharge and net-proton fluctuations [67], p T correlations, particle ratio (chemical) fluctuations [68], but again, within the uncertainties, no clear non-monotonic behaviour, and thus no clear evidence of CP in the energy scan of Au + Au collisions was observed.…”
