On the Next to Leading Order Debye Screening Mass in QGP

  • The next to leading order Debye screening mass in QGP is calculated by taking into accout the damping rate of gluons in the formalism of real time finite temperature QCD,and the infrared singularity in naive calculation is cured without adding to the nonperturbative magnetic screening mass as the cutoff.In addition,the result is shown to be postive and gauge-independent,and is compared with the lattice simulation result.

Abstract: The next to leading order Debye screening mass in QGP is calculated by taking into accout the damping rate of gluons in the formalism of real time finite temperature QCD,and the infrared singularity in naive calculation is cured without adding to the nonperturbative magnetic screening mass as the cutoff.In addition,the result is shown to be postive and gauge-independent,and is compared with the lattice simulation result.
