| Abstract | We report results on event-by-event fluctuations of transverse momentum, Phi (p/sub t/), in pi /sup +/p and K/sup +/p collisions at 250 GeV/c. For the first time, their dependence on rapidity region, transverse momentum acceptance, multiplicity, mean transverse momentum per event, and on the correlation between transverse momentum and multiplicity are systematically presented. The results are compared with those from the PYTHIA Monte Carlo generator. The fluctuations under the same acceptance cuts as used in current heavy- ion experiments are also presented. |
