摘要:
Recent experimental data on the negative correlation between forward energy and transverse energy, which have been reported for the interactions of 14.6A GeV Si28 with Al, Cu, Au, and Pb, 60A and 200A GeV O16 and S32 with S, Cu, Ag, and Au, are investigated by a model based on the description of geometrical properties of nucleus-nucleus collision processes. A parameter, ellipticity e, which might describe the conversion of initial energy into that of radiated final-state hadrons is proposed.

摘要:
A possible universal description of rapidity dependence of multiplicity distributions in high energy e(+)e(-), mu p, hh, hA and AA collisions is proposed based on a cluster mechanism, local charged compensation and its violation. It appears that there exist a statistical connection between multiplicity distribution in a full longitudinal phase space and that in a selected rapidity window with limited size.

摘要:
The physical mechanism of multihadron production in high-energy nondiffractive collisions is discussed based on the quantum coherent state. A remarkable agreement is obtained between the theoretical results and experimental data in respect of the high-order normalized moments at c.m. energies from 11.5 to 900 GeV for the full phase space. Predictions are made for Fermilab Tevatron, CERN Large Hadron Collider, and Superconducting Super Collider energies by using an empirical formula for 〈nND〉 and our relation involving the parameter λ.
