摘要:

在主方程自由解变形的背景下,结合局部BRST上同调,分析了11维时空中无质量的Rarita-Schwinger场和阿贝尔三形式规范场之间的相互作用.在相互作用在耦合常数、局域性、Poincare不变性、Lorentz协变性以及相互作用理论的Lagrangian中最多存在两个导数的假设下,(与自由拉格朗日量中的导数相同),我们证明了D= 0中的引力子既不存在交叉耦合,也不存在自相互作用。[11]唯一可能加到主方程变形解中的项,不过是三种形式规范场的广义陈-西蒙斯项,它对变形拉格朗日量有贡献,但不会修改原来的阿贝尔规范变换。

英文摘要:

The interactions that can be introduced between a massless Rarita-Schwinger field and an Abelian three-form gauge field in eleven spacetime dimensions are analyzed in the context of the deformation of the free solution of the master equation combined with local BRST cohomology. Under the hypotheses of smoothness of the interactions in the coupling constant, locality, Poincare invariance, Lorentz covariance, and the presence of at most two derivatives in the Lagrangian of the interacting theory (the same number of derivatives like in the free Lagrangian), we prove that there are neither cross-couplings nor self-interactions for the gravitino in D=11.The only possible term that can be added to the deformed solution to the master equation is nothing but a generalized Chern-Simons term for the three-form gauge field, which brings contributions to the deformed Lagrangian, but does not modify the original, Abelian gauge transformations.
