Inelastic multiparticle collisions in a parton cascade
نویسنده
چکیده
We elaborate on a new 3+1 dimensional Monte Carlo parton cascade solving kinetic Boltzmann processes including for the first time inelastic multiplication processes (gg ↔ ggg) in a unified manner. The back reaction channel is treated fully consistently, exactly obeying detailed balance. The algorithm can handle, in principle, any specified initial conditions for the freed partons, the latter being on their kinetic mass shell. First full simulations with minijet initial conditions demonstrate that the inclusion of the inelastic channels leads to a very fast kinetic and chemical equilibration and also to an early creation of pressure.

Employing a newly developed pQCD inspired parton cascade we simulate the space time evolution of gluons which are produced initially in a heavy ion collision at RHIC energy. The inelastic gg ↔ ggg interactions are for the first time implemented obeying full detailed balance. The numerical results show that thermalization of gluons is mainly driven by the inelastic gluonic interactions and reach...
متن کاملLocal Monte Carlo implementation of the non-Abelian Landau-Pomeranschuk-Migdal effect.
The non-Abelian Landau-Pomeranschuk-Migdal (LPM) effect arises from the quantum interference between spatially separated, inelastic radiation processes in matter. A consistent probabilistic implementation of this LPM effect is a prerequisite for extending the use of Monte Carlo (MC) event generators to the simulation of jetlike multiparticle final states in nuclear collisions. Here, we propose ...
متن کاملThe role of the gluonic gg ↔ ggg interactions in early thermalization in ultrarelativistic heavy-ion collisions
We “quantify” the role of elastic as well as inelastic gg ↔ ggg pQCD processes in kinetic equilibration within a pQCD inspired parton cascade. The contributions of different processes to kinetic equilibration are manifested by the transport collision rates. We find that in a central Au+Au collision at RHIC energy pQCD Bremstrahlung processes are much more efficient for momentum isotropization c...
متن کاملA Multiparton Model for pp / pp Inelastic Scattering
We have applied a geometrical approach to study pp / pp inelastic scattering over the range of center mass energies from 44.5 to 900 GeV. The multiplicity distributions are described by multiple parton-parton collisions without free parameters. The output seems to be consistent with data and the results are discussed. Exploring the possible connection between impact parameter representation of ...
متن کاملInterplay of Parton and Hadron Cascades in Nucleus-nucleus Collisions at the Cern Sps and Rhic
We introduce a Monte Carlo space-time model for high-energy collisions with nuclei, involving the dynamical interplay of perturbative QCD parton production and evolution, with non-perturbative parton-cluster formation and ‘afterburner’ cascading of formed pre-hadronic clusters plus hadron excitations. This approach allows us to trace the space-time history of parton and hadron degrees of freedo...
