具有Brout-Englert-Higgs效应的理论的可观测谱

On the observable spectrum of theories with a Brout-Englert-Higgs effect

Axel Maas, René Sondenheimer, Pascal Törek

摘要:

在规范理论中,物理的、可观测的谱是由规范不变态组成的。Fröhlich-Morchio-Strocchi机制允许在标准模型中将这些态映射到规范依赖的基本态$W$、$Z$和希格斯态。在具有更一般规范群和希格斯扇区的理论中,情况不再必然如此。我们分类和预测的物理频谱的广泛的这样的理论,特别强调大统一理论的情况下,并表明,基本场和物理粒子的频谱之间的差异经常出现。

英文摘要:

The physical, observable spectrum in gauge theories is made up from gauge-invariant states. The Fröhlich-Morchio-Strocchi mechanism allows in the standard model to map these states to the gauge-dependent elementary $W$, $Z$ and Higgs states. This is no longer necessarily the case in theories with a more general gauge group and Higgs sector. We classify and predict the physical spectrum for a wide range of such theories, with special emphasis on GUT-like cases, and show that discrepancies between the spectrum of elementary fields and physical particles frequently arise.
