Color correlations in QCD plasma

Color correlations in QCD plasma

Perturbative QCD and the random-phase approximation are used to study the current-current correlation function in quark-gluon plasma. The calculations show that there are damped collective oscillations in the system. An estimate of the Debye screening length gives a value of about 0.5 fm at a temper...

Zusammenfassung:Perturbative QCD and the random-phase approximation are used to study the current-current correlation function in quark-gluon plasma. The calculations show that there are damped collective oscillations in the system. An estimate of the Debye screening length gives a value of about 0.5 fm at a temperature of 250 MeV.
