Forward Hemisphere

The collective azimuthal alignment of charged particles is observed inside of two groups of particles, one emitted to the backward and one emitted to the forward hemisphere in the center of mass of symmetric heavy ion collisions. Whereas for Ca+Ca collisions no effect is observed, the alignment is present for Nb+Nb, and is even more pronounced for Au+Au. There exists also a distinct multiplicity and energy dependence of this collective azimuthal alignment.

The pseudorapidity distribution of relativistic singly charged particles produced in high-energy heavy-ion collisions is described by the thermalized cylinder picture. The calculated results are in agreement with the experimental data of lead-induced interactions at 158A GeV/c. PACS Nos.:25.75.-q and 25.75.Dw

The Mean

An equation for parton multiplicity in cascade with the recombination 1 → 2 ⊕ 2 → 1 is derived from a Kolmogorov-Chapman equation and solved. An evolution parameter τ of the cascade depends on the c.m. energy [Formula: see text]; an explicit form of the dependence is obtained from the condition that the mean multiplicity of charged particles in pp, [Formula: see text] collisions be reproduced. A considerable decrease in the mean multiplicity in heavy-ion collisions per pair of the colliding nucleons at high energies is predicted and compared to the parton cascade with no recombination.
