在本文中，我们通过使用新的 Kaluza-Klein (KK) 分解来研究大块无质量 q 型场在余维一膜上的局域化，其中大块 q 型场有两种类型的 KK 模式，即 q 型和 (q− 1) 型模式。第一种模式可能是有质量的或无质量的，而第二种模式都是无质量的。这两种 KK 模式满足两个类薛定谔方程。对于具有有限额外维度的五维膜模型，膜上的大块三态场的频谱由一些大质量束缚三态 KK 模式以及一些沿额外维度具有不同配置的无质量束缚二态模式组成。这些 2-form 模式与从批量 2-form 字段获得的模式不同。对于具有无限额外维度的五维简并 Bloch 膜模型，对于块体 3 型场，获得了一些大质量 3 型共振 KK 模式和相应的无质量 2 型共振模式。
In this paper, we investigate localization of a bulk massless q-form field on codimension-one branes by using a new Kaluza–Klein (KK) decomposition, for which there are two types of KK modes for the bulk q-form field, the q-form and (q− 1)-form modes. The first modes may be massive or massless while the second ones are all massless. These two types of KK modes satisfy two Schrödinger-like equations. For a five-dimensional brane model with a finite extra dimension, the spectrum of a bulk 3-form field on the brane consists of some massive bound 3-form KK modes as well as some massless bound 2-form ones with different configuration along the extra dimension. These 2-form modes are different from those obtained from a bulk 2-form field. For a five-dimensional degenerated Bloch brane model with an infinite extra dimension, some massive 3-form resonant KK modes and corresponding massless 2-form resonant ones are obtained for a bulk 3-form field.
