通过提供希格斯真空外电磁场的合适定义,我们表明在闪片内存在一个带有量子化电荷的单极子-反单极子对,以及一个电磁电流环路。在小 [ital FTHETA][sub [ital W]] 的限制下对内部的相关电荷和电流进行积分,我们恢复了 sphaleron 偶极矩的标准公式。
By providing a suitable definition of the electromagnetic field off the Higgs vacuum, we show that within the sphaleron there is a monopole-antimonopole pair with quantized charges, and a loop of electromagnetic current. On integration of the relevant charges and currents over the interior in the limit of small [ital FTHETA][sub [ital W]], we recover the standard formula for the sphaleron dipole moment.
