| dc.description.abstract | Results are presented on event-by-event fluctuations of transverse momenta pT in central Pb[plus]Pb interactions at 20A, 30A, 40A, 80A, and 158A GeV. The analysis was performed for charged particles at forward center-of-mass rapidity (1.1<y[subscript pi][superscript *]<2.6). Three fluctuation measures were studied: the distribution of average transverse momentum M(p[subscript T]) in the event, the Φp[subscript T] fluctuation measure, and two-particle transverse momentum correlations. Fluctuations of pT are small and show no significant energy dependence in the energy range of the CERN Super Proton Synchrotron. Results are compared with QCD-inspired predictions for the critical point, and with the UrQMD model. Transverse momentum fluctuations, similar to multiplicity fluctuations, do not show the increase expected for freeze-out near the critical point of QCD. | en |
