Results are presented on event-by-event fluctuations of transverse momenta pT in central Pb+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<yπ*<2.6). Three fluctuation measures were studied: the distribution of average transverse momentum M(pT) in the event, the …
