杨-米尔斯理论中的有效标量场

Effective scalar fields in Yang-Mills theories

H. Verschelde, V. I. Zakharov

摘要:

标量场在标准模型中起着至关重要的作用。另一方面,在弱耦合区,标量质量的二次发散是一个未解决的问题。因此,在强耦合区,转向复合场或有效标量场是很自然的。晶格模拟提供了杨-米尔斯理论中“实际存在的”标量场的信息。在连续介质理论方面,对偶模型预测了各种低维真空缺陷的存在,可能包括标量粒子。我们正在寻找两个框架之间的对应关系,晶格现象学和对偶模型,并讨论可能的应用程序的杨米尔斯等离子体理论中的退澄清阶段。不排除有效标量在等离子体动力学中起重要作用。

英文摘要:

Scalar fields play a crucial role in the Standard model. On the other hand, in the weak-coupling regime there is an unsolved problem of the quadratic divergence of scalar masses. Thus, it is natural to turn to composite, or effective scalar fields in the strong-coupling regime. Lattice simulations provide information on the "actually existing" scalar fields in Yang-Mills theories. On the continuum-theory side, dual models predict existence of various low-dimension vacuum defects, including probably scalar particles. We are looking for correspondence between the two frameworks, of lattice phenomenology and dual models, and discuss possible applications to the theory of the Yang-Mills plasma in the deconfining phase. It is not ruled out that the effective scalars play important role in the plasma dynamics.
