一个Kaluza-Klein启发action的手性p-形式及其异常

A Kaluza-Klein inspired action for chiral p-forms and their anomalies

Federico Bonetti, Thomas W. Grimm, Stefan Hohenegger

摘要:

手征p-形式的动力学可以通过一个低维宇称破坏作用来捕获,该作用是由圆上的卡鲁扎-克莱因约化引起的。无质量模是具有标准动力学项和与背景度规的Kaluza-Klein矢量的Chern-Simons耦合的(p-1)形式。质量模是在卡鲁扎-克莱因矢量下带电的p-形式,并允许奇偶奇的一阶动力学项。规范不变性是通过一个类似于Stueckelberg的机制使用(p-1)-形式实现的。Kaluza-Klein矢量的Chern-Simons项由大量p型模在一个环上产生。这些发现是一致的异常和超对称性的六维超引力理论与手征张量多重态。

英文摘要:

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 Stueckelberg-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.
