具有给定能量的Yang-Mills场的半经典解

Semiclassical solution for Yang-Mills field with given energy

Michael Kuchiev

摘要:

本文讨论了杨-米尔斯理论的一个新的经典解,其中欧几里德能量起着参数的作用。瞬子和sphaleron被证明是这个更一般的解决方案的特殊例子。它们的能量参数具有特殊的值,即瞬子的质量为零,裂子的质量为裂子。该解决方案被用来描述隧道过程,这是伴随着拓扑电荷的变化。一个温度范围内,新的解决方案,使这种隧穿更有效的比已知的机制的基础上的瞬子,caloron或sphaleron被发现。

英文摘要:

A new classical solution for the Yang-Mills theory in which the Euclidean energy plays a role of a parameter is discussed. The instanton and sphaleron are shown to be particular examples of this more general solution. The energy parameter for them takes on special values, which are zero and sphaleron mass for the instanton and sphaleron, respectively. The solution is employed to describe the tunneling process, which is accompanied by a variation of the topological charge. A range of temperatures, where the new solution makes this tunneling more effective than the known mechanisms based on the instanton, caloron or sphaleron is found.
