部分规范不变性的标准模型

Standard Model with Partial Gauge Invariance

J. L. Chkareuli, Z. Kepuladze

摘要:

我们认为,一个精确的规范不变性可能会禁用一些通用功能的标准模型,否则可能会表现出自己在高能量。其中之一可能与自发的洛伦兹不变性破坏(SLIV)有关,它可以为QED和Yang-Mills理论提供另一种动力学方法,光子和非阿贝尔规范场以无质量的Nambu-Goldstone玻色子的形式出现。看到一些新的物理预期的关键特征,我们提出部分,而不是精确的规范不变性在扩展SM框架。这一原理以某种最小形式应用于弱超荷规范场B_{mu}及其相互作用,导致B场分量的SLIV出现为无质量的南武-戈德斯通模,并提供了许多独特的洛伦兹喙效应。在低能量下被自然抑制,它们可能在高能物理和天体物理中被探测到。一些最有趣的SLIV过程被认为是在显着的细节。

英文摘要:

We argue that an exact gauge invariance may disable some generic features of the Standard Model which could otherwise manifest themselves at high energies. One of them might be related to the spontaneous Lorentz invariance violation (SLIV) which could provide an alternative dynamical approach to QED and Yang-Mills theories with photon and non-Abelian gauge fields appearing as massless Nambu-Goldstone bosons. To see some key features of the new physics expected we propose partial rather than exact gauge invariance in an extended SM framework. This principle applied, in some minimal form, to the weak hypercharge gauge field B_{mu} and its interactions leads to SLIV with B field components appearing as the massless Nambu-Goldstone modes, and provides a number of distinctive Lorentz beaking effects. Being naturally suppressed at low energies they may become detectable in high energy physics and astrophysics. Some of the most interesting SLIV processes are considered in significant detail.
