摘要:

在形变的耦合常数光滑性、定域性、Lorentz协变性和Poincare不变性的假设下,结合保持每个场的导数个数,研究了具有(3,1)型两柱Young图混合对称性的单个自由无质量张量规范场与一个阿贝尔矢量场之间的相容相互作用.的计算进行的变形理论的帮助下,基于上同调的方法,在反场BRST形式主义的背景下。主要的结果是,在五个时空维度中,这些类型的场之间存在非平凡的交叉耦合,这打破了PT不变性,并允许向量场的规范变换变形,但不允许规范代数变形。

英文摘要:

Under the hypotheses of smoothness in the coupling constant, locality, Lorentz covariance, and Poincare invariance of the deformations, combined with the preservation of the number of derivatives on each field, the consistent interactions between a single free massless tensor gauge field with the mixed symmetry of a two-column Young diagram of the type (3,1) and one Abelian vector field have been investigated. The computations are done with the help of the deformation theory based on a cohomological approach, in the context of the antifield-BRST formalism. The main result is that there exist nontrivial cross-couplings between these types of fields in five spatiotemporal dimensions, which break the PT invariance and allow for the deformation of the gauge transformations of the vector field, but not of the gauge algebra.
