We present a study of event-by-event fluctuations of transverse momentum in πp and Kp collisions at 250 GeV/c and the corresponding PYTHIA Monte Carlo results for πp collisions. The dependence of Φpt on event and particle variables are investigated in detail. We find that Φpt are all negative for different average transverse momentum per event sample. The(More)
A factorial-moment analysis with real (integer and non-integer) phase space partition is applied to + p and K + p collisions at 250 GeV/c. Clear evidence is shown for self-aane rather than self-similar power-law scaling in multiparticle production. The three-dimensional self-aane second-order scaling exponent is determined to be 0.0610.010.
We report results on event-by-event fluctuations of transverse momentum, Phi(p(t)), in pi(+)p and K(+)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(More)

A factorial-moment analysis with real (integer and non-integer) phase space partition is applied to π+p and K+p collisions at 250 GeV/c. Clear evidence is shown for self-affine rather than self-similar power-law scaling in multiparticle production. The three-dimensional self-affine second-order scaling exponent is determined to be 0.061±0.010. a Supported(More)
