论文摘要
通过屏蔽电力和磁性型红外差异，可以估计通过夸克gluon等离子体（QGP）传播的重夸克的阻力和扩散系数。扰动量子染色体动力学（PQCD）中的电型筛选已被广泛研究并用于评估重夸克（HQS）的扩散系数。据我们所知，以前未研究磁筛选在HQS扩散系数中的影响。发现磁性筛选质量对HQS阻力和扩散系数的影响非常重要，并且不应忽略其贡献，以解释重型夸克可观察物的实验数据。
The drag and diffusion coefficients of heavy quarks propagating through quark gluon plasma (QGP) have been estimated by shielding both the electric and magnetic type infra-red divergences. The electric type screening in perturbative quantum chromodynamics (pQCD) has been widely studied and used in evaluating the diffusion coefficient of heavy quarks (HQs). To our knowledge the impact of magnetic screening in diffusion coefficients of HQs is not studied before. It is found that the effect of magnetic screening mass on the drag and diffusion coefficients of HQs is quite significant and its contribution should not be ignored for explaining the experimental data of heavy quark observables.
