Space-time structure of initial parton production in ultrarelativistic heavy ion collisions.
The space and time evolution of initial parton production in ultrarelativistic heavy ion collisions is investigated within the framework of perturbative QCD which includes both initial and final state radiations. Uncertainty principle is used to relate the life time of a radiating parton to its virtuality and momentum. The interaction time of each hard or semihard parton scattering is also take...
متن کاملScreening of initial parton production in ultrarelativistic heavy-ion collisions
Screening of initial parton production due to the presence of on-shell partons in high-energy heavy-ion collisions is discussed. It is shown that the divergent cross sections in the calculation of parton production can be regulated self-consistently without an ad hoc cut-off, and that the resultant parton production and transverse energy production rate are finite. Consequences on the energy de...
متن کاملParton Equilibration in Ultrarelativistic Heavy Ion Collisions
Medium effects which include color screening and Landau-Pomeranchuk-Migdal suppression of induced radiation are discussed in connection with the equilibration of dense partonic system in ultrarelativistic heavy ion collisions. Taking into account of these medium effects, the equilibration rate for a gluonic gas are derived and the consequences are discussed.
متن کاملDilepton production in ultrarelativistic heavy-ion collisions.
Many probes have been proposed to map out the behaviour of hot and dense hadronic matter and also to highlight its eventual transition to a plasma of quarks and gluons. It is outside the scope of this talk to review them all or even partially: we will concentrate on electromagnetic radiation and more specifically on the emission of thermal lepton pairs. Those suffer minimal final state interact...
متن کاملCluster Production in Ultrarelativistic Heavy Ion Collisions
. . . may prove an interesting tool to extract physical quantities of the fireball, once the formation process has been understood. We assume an emission function of the form [1] with gaussian source parametrization and local thermal equilibrium distributions for nucleons in the hot, central reaction region. Using a Wigner function coalescence mechanism [2], we obtain a formula for the invarian...
