We study relaxation properties of two-body collisions on the mean-field level. We show that this process exhibits multiscaling asymptotic behavior as the underlying distribution is characterized by an infinite set of nontrivial exponents. These nonequilibrium relaxation characteristics are found to be closely related to the steady state properties of the system.

The current normalization of the cross section of inclusive high-p T particle production in deuteron-gold collisions measured at RHIC relies on Glauber model calculations for the inelastic dAu cross section. These calculations should be corrected for diffrac-tion. Moreover, they miss the Gribov's inelastic shadowing which makes nuclei more transparent (color transparency) and reduce the inelast...

We discuss the multiplicity distribution for highest accessible energies of ppand p̄pinteractions from the point of view of the multiparton collisions. The inelastic cross sections for the single, σ1, and multiple (double and, presumably, triple, σ2+3) parton collisions are extracted from the analysis of the experimental data on the multiplicity distribution up to the Tevatron energies. It follo...

A potential energy surface for the lowest quartet electronic state ((4)A(')) of lithium trimer is developed and used to study spin-polarized Li+Li(2) collisions at ultralow kinetic energies. The potential energy surface allows barrierless atom exchange reactions. Elastic and inelastic cross sections are calculated for collisions involving a variety of rovibrational states of Li(2). Inelastic co...

Interactions of solitary waves in a cylindrically confined Bose-Einstein condensate are investigated by simulating their head-on collisions. Slow vortex rings and fast solitons are found to collide elastically contrary to the situation in the three-dimensional homogeneous Bose gas. Strongly inelastic collisions are absent for low density condensates but occur at higher densities for intermediat...

The binary collision dynamics of Dg,3/2 ground state scandium atoms is studied from first principles. We employ 30 coupled diabatic ab initio potentials in a coupled-channels study of the scattering dynamics of cold and ultracold scandium atoms in external magnetic fields. Due to the long-ranged magnetic dipolar interaction, the field dependence of the cross section does not follow the threshol...

Charm production in antiproton-nucleus collisions at the J/ψ and the ψ ′ thresholds Abstract We discuss the production of charmonium states in antiproton-nucleus collisions at the ψ ′ threshold. It is explained that measurements in ¯ pA collisions will allow to get new information about the strengths of the inelastic J/ψN, ψ ′ N interaction, on the production of Λc and ¯ D in charmonium-nucleon...

Molecular dynamics and DSMC models for energy transfer in argon dimer argon monomer collisions are compared. The inelastic collision number for these collisions is evaluated, and found to decrease significantly when gas temperature increases.
