摘要:

我们在包含非定域相互作用的手征夸克模型的背景下研究了强相互作用物质在强外磁场下的行为。特别地,我们分析了恒定磁场对零温和有限温手征夸克凝聚的影响,研究了去禁闭和手征恢复的临界温度,并讨论了所观察到的“磁催化”和“逆磁催化”效应。此外,我们在这个框架中分析的行为的$π^0$质量和衰变常数。将非定域手征夸克模型的预言与格点量子色动力学的结果进行了比较。

英文摘要:

We study the behavior of strongly interacting matter under a strong external magnetic field in the context of chiral quark models that include nonlocal interactions. In particular, we analyze the influence of a constant magnetic field on the chiral quark condensates at zero and finite temperature, studying the deconfinement and chiral restoration critical temperatures and discussing the observed "magnetic catalysis" and "inverse magnetic catalysis" effects. In addition, we analyze in this framework the behavior of the $π^0$ mass and decay constant. The predictions of nonlocal chiral quark models are compared with results obtained in lattice QCD.
