论文摘要
我们通过构建一系列两种参数有限的保守量来证实Podolsky的广义电动力学的稳定性，包括规范能量弹药张量。此外，我们评估了BV抗场形式主义中该较高衍生系统的过渡振幅，并通过选择适当的固定尺寸的费用来获得理想的广义辐射仪条件。在Lagrangian BRST共同学的框架内，我们介绍了Podolsky模型中一致相互作用的构造，以及在变形过程后集中精力在主操作的Antighost Number零部分时，我们得到了Podolsky理论的非亚伯利亚膨胀。此外，我们利用Dirac-Bergmann算法方法计算了产生的较高衍生系统中物理自由度的数量，并表明如果将一致的相互作用包含在自由理论中，则它是不变的。
We confirm the stability of Podolsky's generalized electrodynamics by constructing a series of two-parametric bounded conserved quantities which includes the canonical energy-momentum tensors. In addition, we evaluate the transition-amplitude of this higher derivative system in BV antifield formalism and obtain the desirable generalized radiation gauge condition by choosing appropriate gauge-fixing fermion. Within the framework of Lagrangian BRST cohomology, we present the constructions of consistent interactions in Podolsky's model and when concentrating on the antighost number zero part of the master action after deformation process, we get the non-Abelian extensions of the Podolsky's theory. Furthermore, we calculate the number of physical degrees of freedom in the resulting higher derivative system utilizing Dirac-Bergmann algorithm method and show that it is unchanged if the consistent interactions are included into the free theory.
