积分型Yang-Mills方程通过SU(2)单极子的直接检验

A direct test of the integral Yang-Mills equations through SU(2) monopoles

C. P. Constantinidis, L. A. Ferreira, G. Luchini

摘要:

我们使用SU(2)的t Hooft-Polyakov组态及其BPS版本来检验Yang-Mills理论的积分方程。这些积分方程包含两个在微分杨-米尔斯方程中没有出现的(复)参数,如果它们被认为是任意的,那么就意味着非阿贝尔规范理论(但不是阿贝尔规范理论)拥有无穷多个积分方程。对于静态配置,这些参数中只有一个是相关的。我们将积分杨-米尔斯方程展开为该参数的幂级数,并证明了t Hooft-Polyakov方法及其BPS形式满足该展开式的一阶和二阶积分方程。我们的结果指出了探索这样的一个无穷大的积分方程的整体性质的杨-米尔斯理论的物理后果的重要性。

英文摘要:

We use the SU(2) 't Hooft-Polyakov monopole configuration, and its BPS version, to test the integral equations of the Yang-Mills theory. Those integral equations involve two (complex) parameters which do not appear in the differential Yang-Mills equations, and if they are considered to be arbitrary it then implies that non-abelian gauge theories (but not abelian ones) possess an infinity of integral equations. For static monopole configurations only one of those parameters is relevant. We expand the integral Yang-Mills equation in a power series of that parameter and show that the 't Hooft-Polyakov monopole and its BPS version satisfy the integral equations obtained in first and second order of that expansion. Our results points to the importance of exploring the physical consequences of such an infinity of integral equations on the global properties of the Yang-Mills theory.
