论文摘要
在本文中,我们提出了一个领域重新定义不变的拉格朗日乘数(LM)形式主义,其中引入了类似于Lee-Yang Ghosts的新的类似幽灵的领域。这些幽灵字段需要恢复LM理论标准路径积分的字段重新定义不变性,同时恢复了由于LM字段而取消额外贡献。我们认为,来自LM领域的标准LM形式主义中的额外自由度应该取消幽灵领域的自由度。因此,在领域重新定义不变的形式主义是不存在与LM领域相关的自由度的加倍。
In this paper, we propose a field redefinition invariant Lagrange multiplier (LM) formalism in which new ghost-like fields, analogous to Lee-Yang ghosts, are introduced. These ghost fields are required to restore the field redefinition invariance of the standard path integral of the LM theory and, at the same time, to cancel the additional contributions due to the LM fields. We argue that the extra degrees of freedom in the standard LM formalism, coming from the LM fields, should cancel against the degrees of freedom of the ghost fields. Hence, in the field redefinition invariant formalism the doubling of degrees of freedom, associated with the LM fields, is absent.
