本文计算了在Polyakov圈背景下,轻夸克热化等离子体中重夸克的输运系数、阻力和动量扩散。在非平凡的Polyakov环背景下计算了夸克热质量和胶子德拜质量。在一个Polyakov圈夸克介子(PQM)模型中估计了夸克质量和Polyakov圈。在矩阵模型下,计算了在Polyakov圈背景下重夸克和轻部分子的散射振幅。我们还将计算结果与格点QCD模拟的Polyakov环参数进行了比较。我们研究了重夸克阻力系数和扩散系数对温度和动量的依赖性。我们发现,阻力系数的温度依赖性很弱,这对理解RHIC和LHC能区的重夸克观测值可能起着关键作用。
We calculate the transport coefficients, drag and momentum diffusion, of a heavy quark in a thermalized plasma of light quarks in the background of Polyakov loop. Quark thermal mass and the gluon Debye mass are calculated in a non-trivial Polyakov loop background. The constituent quark masses and the Polyakov loop is estimated within a Polyakov loop quark meson (PQM) model. The relevant scattering amplitudes for heavy quark and light partons in the background of Polyakov loop has been estimated within the matrix model. We have also compared the results with the Polyakov loop parameter estimated from lattice QCD simulations. We have studied the temperature and momentum dependence of heavy quark drag and diffusion coefficients. It is observed that the temperature dependence of the drag coefficient is quite weak which may play a key role to understand heavy quark observables at RHIC and LHC energies.
