$U(1)$规范场在Bloch膜上的Chumbes-Holf da Silva-Hott定域
$U(1)$ Gauge Field Localization on Bloch Brane with Chumbes-Holf da Silva-Hott Mechanism
摘要：
我们采用Chumbes-Holf da Silva-Hott（CHH）机制研究了$U(1)$规范场在Bloch膜上的（准）定域.本文讨论了四种Bloch膜解的$U(1)$规范场的定域性：原始Bloch膜解、广义Bloch膜解、退化Bloch膜解I和II。在CHH机制下，我们发现规范场Kaluza-Klein模的质量谱是连续的，只有规范场的零模局域在膜上.对于质量模，只在简并的Bloch膜上存在共振模。
英文摘要：
We follow the Chumbes-Holf da Silva-Hott (CHH) mechanism to study the (qusi-)localization of $U(1)$ gauge field on the Bloch brane. The localization of $U(1)$ gauge field is discussed for four kinds of Bloch brane solutions: the original Bloch brane solution, the generalized Bloch brane solution, and the degenerate Bloch brane solutions I and II. With the CHH mechanism, we find that the mass spectrum of the gauge field Kaluza-Klein modes is continuous and only the zero mode of the gauge field is localized on the brane. For the massive modes, there exist resonant modes only on the degenerate Bloch branes.
