微电荷与磁单极

Minicharges and Magnetic Monopoles

Felix Bruemmer, Joerg Jaeckel

摘要:

在标准模型的扩展中,在普通电磁场U(1)和额外的“隐藏扇区”U(1)之间有一个动力学混合项,微带电粒子自然产生。本文研究了这些粒子与磁单极子的相容性。我们发现,角动量量子化只允许普通和隐藏的电荷的某些组合。以其中一个U(1)起源于自发破缺的SU(2)为例,我们证明了所允许的单极子类型恰好是t Hooft-Polyakov单极子。

英文摘要:

Minicharged particles arise naturally in extensions of the Standard Model with a kinetic mixing term between the ordinary electromagnetic U(1) and an extra "hidden sector" U(1). In this note we study the compatibility of these particles with the existence of magnetic monopoles. We find that angular momentum quantization allows only certain combinations of ordinary and hidden monopole charge. Using the example where one of the U(1)s originates from a spontaneously broken SU(2), we demonstrate that exactly the allowed types of monopoles arise as 't Hooft-Polyakov monopoles.
