A Comparison of different measures for dynamical event-mean transverse momentum fluctuation
Liu Lianshou, Fu Jinghua
Various measures for the dynamical event-mean transverse momentum fluctuation are compared with the real dynamical fluctuation using a Monte Carlo model. The variance calculated fr…
A Monte Carlo Study of the Levy Stability and Multifractal Spectrum in e+e- collisions
Chen Gang, Liu Lianshou
The Levy stability analysis is carried out for e+e- collisions at Z^0 mass using Monte Carlo method. The Levy index μis found to be μ=1.701 +- 0.043. The self-similar generalized d…
On the Phase Space Partition in High Energy Collisions
Liu Lianshou
In high energy hadron-hadron and e+e- collisions, to isolate a part of the phase space in multi-hadron final states is necessary for exploring the underlying dynamics. It is shown…
On the Scale of Visible Jets in High Energy Electron-Positron Collisions
Liu Lianshou, Chen Gang, Fu Jinghua
A study of the dynamical fluctuation property of jets is carried out using the Monte Carlo method. The results suggest that, the anisotropy of dynamical fluctuations in the hadroni…
Thermal Freeze-out and Longitudinally Non-uniform Collective Expansion Flow in Relativistic Heavy Ion Collisions
FENG Shengqin, LIU Feng, LIU Lianshou
The non-uniform longitudinal flow model (NUFM) propsed recently is extended to include also transverse flow. The resulting longitudinally non-uniform collective expansion model (NU…
Thermal Equilibration and Ellipsoidal Expansion of Rotationally-Symmetrical Longitudinal Flow in Relativistc Heavy Ion Collisions
Feng Shengqin, Liu Feng, Liu Lianshou
A rotationally-symmetrical ellipsoidal flow model is proposed for the relativistic heavy-ion collisions and compared with the 14.6 A GeV/c Si-Al and 10.8 A GeV/c Au-Au collision da…
