修正的二维Proca理论:离壳幂零对称及其数学和物理意义

Modified 2D Proca theory: off-shell nilpotent symmetries and their mathematical as well as physical implications

R. P. Malik

摘要:

我们导出了包含伪标量场的2维(1 + 1)Stueckelberg修正的Proca理论的两个等价拉格朗日密度的离壳幂零Becchi-Rouet-Stora-Tyrons(BRST)、反BRST、(反)co-BRST、玻色子和鬼标度对称变换.我们还讨论了代数合适的离散对称变换的理论。最后,我们证明了上述连续和离散对称性在微分几何的背景下的相关性,并建立我们目前的大规模二维理论是一个易于处理的霍奇理论的场论模型。我们目前研究的一个关键的新观察是Curci-Ferrari(CF)型限制的出现,即使在我们目前的大规模二维阿贝尔1-形式规范理论的情况下。我们还指出了上述赝标量场在本理论中的数学和物理意义。

英文摘要:

We derive the off-shell nilpotent Becchi-Rouet-Stora-Tyutin (BRST), anti-BRST, (anti-)co-BRST, a bosonic and the ghost-scale symmetry transformations for a couple of equivalent Lagrangian densities of the two (1 + 1)-dimensional (2D) Stueckelberg-modified version of Proca theory which also incorporates a pseudo-scalar field. We also discuss algebraically suitable discrete symmetry transformations of the theory. Finally, we demonstrate the relevance of the above continuous and discrete symmetries in the context of differential geometry and establish that our present massive 2D theory is a tractable field theoretic model for the Hodge theory. One of the key novel observations of our present investigation is the appearance of Curci-Ferrari (CF) type restrictions even in the case of our present massive 2D Abelian 1-form gauge theory. We also point out the mathematical as well as physical implications of the above pseudo-scalar field in our present theory.
