超复规范场理论中的自发对称性破缺与弦缺陷

Spontaneous symmetry breaking, and strings defects in hypercomplex gauge field theories

R. Cartas-Fuentevilla, O. Meza-Aldama

摘要:

受弦论降维过程中分裂复结构的出现以及作为副产品出现的理论的启发,我们研究了阿贝尔规范场理论的超复表述,方法是在通常的复单位中加入一个新的复单位。与$U(1)$规范场理论相关的传统墨西哥帽势的超复数形式对应于具有两个实分量的{ \it hybrid}势,并且以$U(1)\times SO(1,1)$作为对称群。每个分量对应于帽子势的变形,并出现新的简并真空。超复数电动力学将显示出新的性质,例如矢量和标量希格斯场的运行质量的自发对称性破缺场景,以及Aharonov-Bohm型弦缺陷作为精确解;这些拓扑缺陷只能通过带电粒子的量子干涉通过规范不变的环积分来检测。在一个特定的限制,{ \it双曲}电动力学不承认拓扑缺陷与连续对称性

英文摘要:

Inspired by the appearance of split-complex structures in the dimensional reduction of string theory, and in the theories emerging as byproducts, we study the hyper-complex formulation of Abelian gauge field theories, by incorporating a new complex unit to the usual complex one. The hypercomplex version of the traditional Mexican hat potential associated with the $U(1)$ gauge field theory, corresponds to a {\it hybrid} potential with two real components, and with $U(1)\times SO(1,1)$ as symmetry group. Each component corresponds to a deformation of the hat potential, with the appearance of a new degenerate vacuum. Hypercomplex electrodynamics will show novel properties, such as the spontaneous symmetry breaking scenarios with running masses for the vectorial and scalar Higgs fields, and the Aharonov-Bohm type strings defects as exact solutions; these topological defects may be detected only by quantum interference of charged particles through gauge invariant loop integrals. In a particular limit, the {\it hyperbolic} electrodynamics does not admit topological defects associated with continuous symmetries
