电磁德拜质量在Gribov-Zwanziger作用量中的研究

Electromagnetic Debye mass within Gribov-Zwanziger action

Aritra Bandyopadhyay

AI总结:

本研究在Gribov-Zwanziger作用量框架下计算了电磁德拜质量,并展示了其在评估QED系统中重夸克势能的应用,为非微扰QCD计算奠定基础。

摘要:

在本研究中,我们通过计算包含有效夸克圈的单圈光子极化张量时间分量的静态极限,研究了电磁德拜质量。这些有效夸克是在Gribov-Zwanziger作用量框架内考虑的,从而纳入了必要的非微扰效应。作为学术练习,我们还展示了这一Gribov修正的德拜质量的一个应用,即利用它来评估QED系统中重夸克势能的实部和虚部。对电磁德拜质量的计算以及相应的重夸克势能估计,可以被视为在非微扰领域进一步进行实际QCD计算的垫脚石。

英文摘要:

In the present study we have investigated the electromagnetic Debye mass by computing the static limit of the temporal component of the one-loop photon polarization tensor involving effective quarks in the loop. These effective quarks have been considered within the Gribov-Zwanziger action, thereby incorporating the necessary non-perturbative effects. As an academic exercise, we have also shown one of the applications of this Gribov modified Debye mass by using it to evaluate the real and imaginary parts of the heavy quark potential in a QED system. This computation of the electromagnetic Debye mass and the corresponding estimations of the heavy quark potential can be seen as stepping stones in the direction of further practical QCD calculations in the non perturbative domain.
