Dilepton 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...
متن کاملModeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
متن کاملMinijet-associated dilepton production in ultrarelativistic heavy ion collisions.
Dilepton production associated with minijets is calculated in ultrarela-tivistic heavy ion collisions using the first order approximation of the dilepton fragmentation functions of quarks and gluons. The full QCD evolution of the fragmentation functions is also studied. We find that the dilepton pairs from the fragmentation of minijets are comparable to direct Drell-Yan at √ s = 200 AGeV for sm...
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...
