摘要:

研究了在标量物质场存在下,在极大阿贝尔规范量子化的SU(2)Yang-Mills理论的全阶乘法重整化问题。最大阿贝尔规范的非线性特征要求在Faddeev-Popov鬼中引入四次相互作用项,这是该规范的一个众所周知的特征。我们表明,当标量物质场的引入,第二四次之间的相互作用项标量场和Faddeev-Popov鬼自然出现。一个BRST不变的行动占这些四次相互作用项被确定和证明是乘法重整化的代数重整化过程的所有订单。

英文摘要:

We address the issue of the all order multiplicative renormalizability of SU(2) Yang-Mills theories quantized in the maximal Abelian gauge in presence of scalar matter fields. The non-linear character of the maximal Abelian gauge requires the introduction of quartic interaction terms in the Faddeev-Popov ghosts, a well known feature of this gauge. We show that, when scalar matter fields are introduced, a second quartic interaction term between scalar fields and Faddeev-Popov ghosts naturally arises. A BRST invariant action accounting for those quartic interaction terms is identified and proven to be multiplicative renormalizable to all orders by means of the algebraic renormalization procedure.
