高温长程色磁场

Long range chromomagnetic fields at high temperature

Sergey Antropov, Michael Bordag, Vadim Demchik, Vladimir Skalozub

摘要:

在SU(2)胶子动力学中计算了高温阿贝尔色磁场中中性胶子的磁质量。值得注意的是,这种类型的字段是在高温下自发产生。质量的计算可以从考虑单圈偏振张量的Schwinger-Dyson方程或在晶格上的蒙特卡罗模拟中进行。在后一种情况下,针对多个晶格测量穿透格片的平均磁通量。这两种计算结果是一致的,并导致零磁质量。讨论了所得结果的一些应用。

英文摘要:

The magnetic mass of neutral gluons in Abelian chromomagnetic field at high temperature is calculated in SU(2)$ gluodynamics. It is noted that such type fields are spontaneously generated at high temperature. The mass is computed either from the Schwinger-Dyson equation accounting for the one-loop polarization tensor or in Monte-Carlo simulations on a lattice. In latter case, an average magnetic flux penetrating a plaquette is measured for a number of lattices. Both calculations are in agreement with each other and result in zero magnetic mass. Some applications of the results obtained are discussed.
