摘要:

在本文中,我们解决的问题,局域化的费米子状态的稳定畴壁结。研究的重点是在十维时空中,六个独立的8维畴壁相交形成4维结的后果。这与通过畴壁结的形成弛豫到三维空间的机制有关。该模型是基于六个散装实标量场,在其破碎阶段,原型的希格斯场的phi-4模型,是这样的费米子和标量模式绑定到域壁的零模式和一个单一的大质量的束缚态,它可以被视为一个两级系统,至少在足够低的能量。在结内部,我们利用一些状态在统计上更有利的事实来解决约束基本费米子的味数的可能性。

英文摘要:

In this paper we address the problem of localizing fermion states on stable domain walls junctions. The study focus on the consequences of intersecting six independent 8d domain walls to form 4d junctions in a ten-dimensional spacetime. This is related to the mechanism of relaxing to three space dimensions through the formation of domain wall junctions. The model is based on six bulk real scalar fields, the phi-4 model in its broken phase, the prototype of the Higgs field, and is such that the fermion and scalar modes bound to the domain walls are the zero mode and a single massive bound state, which can be regarded as a two level system, at least at sufficiently low energy. Inside the junction, we use the fact that some states are statistically more favored to address the possibility of constraining the flavor number of the elementary fermions.
