摘要:

我们证明了具有BRST对称性软破缺的夸克-胶子模型的重整化性,它解释了夸克和胶子关联函数的大距离行为的改变。利用软破沃德恒等式,证明了该方法对所有阶微扰理论都是有效的.

英文摘要:

We prove the renormalizability of a quark-gluon model with a soft breaking of the BRST symmetry, which accounts for the modification of the large distance behavior of the quark and gluon correlation functions. The proof is valid to all orders of perturbation theory, by making use of softly broken Ward identities.
