Abstract

Abstract We propose a general framework to study BRST-related transformations. We investigate different forms of BRST and BRST-related symmetries, realized within a prototypical first-class system, including ordinary BRST, anti-BRST, dual-BRST, anti-dual-BRST and additional sets of new BRST-related symmetries. We identify a precise discrete group of symmetries of the ghost sector, responsible for connecting the various forms of BRST-related transformations. Their distinct roles in different Hamiltonian and Lagrangian approaches are clarified. As a unifying framework, we use a gauge invariant prototypical first-class system encompassing an extensive class of physical models.

关于BRST和BRST相关对称性的统一框架

摘要本文提出了一个研究brst相关变换的通用框架。我们研究了在一类系统中实现的不同形式的BRST和BRST相关对称，包括普通BRST、反BRST、双BRST、反双BRST和新的BRST相关对称的附加集。我们确定了幽灵部门的精确离散对称组，负责连接各种形式的brst相关转换。阐明了它们在不同的哈密顿和拉格朗日方法中的独特作用。作为一个统一的框架，我们使用一个规范不变的原型一级系统，它包含了广泛的物理模型。

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
