酉的反常 Master Ward 恒等式及其与 Wess-Zumino 条件、BV 形式体系和 $L_\infty$-代数的联系

Unitary, anomalous Master Ward Identity and its connections to the Wess-Zumino condition, BV formalism and $L_\infty$-algebras

AI总结:

本文在 C*-代数 QFT 构造中利用微扰论,证明酉的反常 Master Ward 恒等式中的上闭链条件联系于 Wess-Zumino 一致性关系及 BV 反常一致性关系,后者等价于相关 $L_\infty$-代数的广义 Jacobi 恒等式。

摘要:

Buchholz 与本文作者之一提出的 QFT 的 C*-代数构造依赖于时空的因果结构和一个经典拉格朗日量。在我们此前的一篇论文中,我们向该构造引入了附加结构,即一种对称性作用,它与重整化条件的固定有关。该作用刻画了反常,并满足一个上闭链条件,这一条件被概括在酉的反常 Master Ward 恒等式中。在这里,我们(利用微扰论)展示该上闭链条件如何与 Wess-Zumino 一致性关系以及 BV 形式体系中反常的一致性关系相关联,其中后者是相关 $L_\infty$-代数的广义 Jacobi 恒等式。

英文摘要:

The C*-algebraic construction of QFT by Buchholz and one of us relies on the causal structure of spacetime and a classical Lagrangian. In one of our previous papers we have introduced additional structure into this construction, namely an action of symmetries, which is related to fixing renormalisation conditions. This action characterizes anomalies and satisfies a cocycle condition which is summarized in the unitary anomalous Master Ward identity. Here (using perturbation theory) we show how this cocycle condition is related to the Wess-Zumino consistency relation and the consistency relation for the anomaly in the BV formalism, where the latter is the generalized Jacobi identity for the associated $L_\infty$-algebra.
