| 摘 要： | 采用实时有限温度下的QCD,考虑到胶子的衰减率计算了QGP中次领头阶得拜屏蔽质量的贡献,克服了通常计算中的红外发散的困难,且不必引入非微扰的磁屏蔽质量作红外截断.指出了所得结果的正定性和规范无关性并与格点模拟的结果进行了比较.

| 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. |
