文摘A self-consistent calculation method about the damping rates of fast moving particles in QCP is proposed within the real time finite temperature QCD formalism.And the infrared divergence in the naive calculation is overcome without adding by hand a magnetic screening mass as the infrared cutoff.For weak coupling QCD toe damping rates of the fast moving gluon and quark are obtained and their relaxation times in RICH and LHC scales are estimated.
