论文摘要
在有限温度下，在Gribov-Zwanziger方法中，用重新摄动方法计算了一对重夸克之间的相互作用电位。重新召开的循环校正使潜在的复合物。尽管如预期的那样，实际部分是在热介质中进行筛选并变短的，但假想部分的强度随温度的增加，并且与实际部分相当，这与HTL方法中先前的计算截然不同。这意味着，颜色筛选和Landau阻尼都在热培养基中的浓风味黑龙解离时起着重要作用。
The interaction potential between a pair of heavy quarks is calculated with resummed perturbation method in Gribov-Zwanziger approach at finite temperature. The resummed loop correction makes the potential complex. While the real part is, as expected, screened and becomes short-ranged in hot medium, the strength of the imaginary part increases with temperature and is comparable with the real part, which is very different from the previous calculation in HTL approach. This means that, both the color screening and Landau damping play important role in the dissociation of heavy flavor hadrons in hot medium.
