具有Yang-Mills规范对称性的稳定高阶导数理论

A stable higher-derivative theory with the Yang-Mills gauge symmetry

D. S. Kaparulin

摘要:

给出了一个具有非阿贝尔规范对称性的高导数理论的例子。在自由极限下,该模型描述了向量场的多重态,服从扩展的Chern-Simons方程。该理论允许一个二阶守恒张量,其00分量可以从下面有界或无界,这取决于模型参数。如果守恒张量有一个有界的00-分量,则动力学是稳定的。运动方程是非拉格朗日方程。

英文摘要:

An example of higher-derivative theory with a non-Abelian gauge symmetry is proposed. In the free limit, the model describes the multiplet of vector fields, being subjected to the extended Chern-Simons equations. The theory admits a single second-rank conserved tensor, whose 00-component can be bounded or unbounded from below depending on the model parameters. If the conserved tensor has a bounded 00-component, the dynamics is stable. The equations of motion are non-Lagrangian.
