Rapidity, azimuthal, and multiplicity dependence of mean transverse momentum and transverse momentum correlations in $\pi^{+}p$ and $K^{+}p$ collisions in $\sqrt{s}$=22 GeV / NA22 Collaboration
Rapidity, azimuthal and multiplicity dependence of mean transverse momentum and transverse momentum correlations of charged particles is studied in pi/sup positive and K/sup positive collisions at 250 GeV/c incident beam momentum. For the first time, it is found that the rapidity dependence of the two-particle transverse momentum correlation is different from that of the mean transverse momentum, but both have similar multiplicity dependence.

A Monte Carlo study on cone-angle property of the quark- and gluon- jets identified by b-tag method / Chen Gang ; Liu, Lian-Shou
Quark and gluon jets are studied in three-jet events generated by Jetset 7.4 and Herwig 5.9 at s/sup 1/2/ = 91.2 GeV. The quark jets are identified by b-tag tracing, and the remaining jet is then defined as the gluon jet. [...]

Entropy Analysis in $\pi^{+}p$ and $K^{+}p$ Collisions at $\sqrt{s}=22$ GeV / NA22 Collaboration
The entropy properties are analyzed by Ma's coincidence method in $\pi^{+}\rp$ and $\rK^{+}\rp$ collisions of the NA22 experiment at 250 GeV/$c$ incident momentum. By using the R\'{e}nyi entropies, we test the scaling law and additivity properties in rapidity space. [...]

Transverse-momentum fluctuations in $\pi^{+}p$ and $K^{+}p$ collisions at 250 GeV/c / NA22 Collaboration
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.

Thermal freeze-out and longitudinally nonuniform collective expansion flow in relativistic heavy ion collisions / Feng Sheng Qin ; Liu Feng ; Lian Shou Liu
The nonuniform longitudinal flow model (NUFM) proposed recently is extended to include also the transverse flow. The resulting longitudinally nonuniform collective expansion model (NUCEM) is applied to the calculation of the rapidity distribution of kaons, lambdas and protons in relativistic heavy ion collisions at CERN-SPS energies.

Monte Carlo study on the properties of gluon and quark jets / Kun Shi Zhang ; Gang, Chen ; Mei Ling Yu ; Lian Shou Liu
The 3-jet events produced in e/sup +/e/sup -/ collisions at 91.2 GeV have been studied using Monte Carlo method. After applying two angular cuts the three angles between the jets are used to identify the individual jet in 3-jet events. [...]

Self-affine analysis for the dynamical fluctuations inside jets produced in high energy hadron-hadron collisions / Yin Jian Wu ; Liu Feng ; Lian Shou Liu
A self-affine analysis is performed on the jets (minijets) produced in proton- antiproton collisions at CERN-SppS collider energy. The jets are identified by the "Cone algorithm". [...]

Self-affine fractality and multifractal spectrum of $\pi^{+}p$ and $K^{+}p$ collisions at 250 GeV/c / Lian Shou Liu (Inst of Particle Phys)
The results of a self-affine factorial moments analysis in the multiparticle final states of 250 GeV/c pi /sup +/p and K/sup +/p collisions with real partition number M are presented and compared with those of 400 GeV/c pp collisions from NA27. The inverse Poisson transform method is applied and the information dimension D/sub I/, the correlation dimension nu as well as the multifractal spectrum f( alpha ) are presented. [...]

Monte Carlo study of the dynamical-fluctuation property of the hadronic system inside jets / Lian Shou Liu ; Chen Gang ; Fu Jing Hua
A study of the dynamical fluctuation property of jets is carried out using the Monte Carlo method. The results suggest that, unlike the average properties of the hadronic system inside jets, the anisotropy of dynamical fluctuations in these systems changes abruptly with the variation of the cut parameter y/sub cut/.
