手性 p 型的动力学可以通过由圆上的卡鲁扎-克莱因还原激发的低维宇称破坏行为来捕获。无质量模式是 (p−1) 形式，具有标准动力学项和与背景度量的 Kaluza-Klein 向量的 Chern-Simons 耦合。质量模式是卡鲁扎-克莱因矢量下带电的 p 型，并允许宇称奇数一级动力学项。规范不变性是通过使用 (p−1) 形式的类似 Stückelberg 的机制来实现的。 Kaluza-Klein 向量的 Chern-Simons 项是由大量 p 型模式在一个循环中生成的。这些发现与手性张量多重态六维超引力理论的异常和超对称性一致。
The dynamics of chiral p-forms can be captured by a lower-dimensional parity-violating action motivated by a Kaluza–Klein reduction on a circle. The massless modes are (p−1)-forms with standard kinetic terms and Chern–Simons couplings to the Kaluza–Klein vector of the background metric. The massive modes are p-forms charged under the Kaluza–Klein vector and admit parity-odd first-order kinetic terms. Gauge invariance is implemented by a Stückelberg-like mechanism using (p−1)-forms. A Chern–Simons term for the Kaluza–Klein vector is generated at one loop by massive p-form modes. These findings are shown to be consistent with anomalies and supersymmetry for six-dimensional supergravity theories with chiral tensor multiplets.
