BV-形式中背景场方法下Yang-Mills理论的乘性重整化

Multiplicative renormalizability of Yang-Mills theory with the background field method in the BV-formalism

Igor A. Batalin, Klaus Bering, Peter M. Lavrov, Igor V. Tyutin

摘要:

利用背景场方法和BV-形式研究了四维Yang-Mills理论的规范不变重整化问题,通过在背景场和参数中引入反场伙伴,得到了一个关于反括号齐次的经典主方程.所构造的模型可以通过引入反项的标准方法进行重整化。这个模型不具有(精确的)乘法可重整性,但它在物理部分具有这种性质(准乘法可重整性)。

英文摘要:

Studying the gauge-invariant renormalizability of four-dimensional Yang-Mills theory using the background field method and the BV-formalism, we derive a classical master-equation homogeneous with respect to the antibracket by introducing antifield partners to the background fields and parameters. The constructed model can be renormalized by the standard method of introducing counterterms. This model does not have (exact) multiplicative renormalizability but it does have this property in the physical sector (quasimultiplicative renormalizability).
