摘要
En 中文
We newly revisit the gauge non-invariant chiral Schwinger model with a = I in view of the chain structure. As a result, we show that the Dirac brackets can be easily read off from the exact symplectic algebra of second-class constraints. Furthermore, by using an improved BFT embedding preserving the chain structure, we obtain the desired gauge invariant action including a new type of Wess-Zumino term. (c) 2005 Elsevier B.V.
