摘要
With proposing a unified description of the fields variation at the level of generating functional, we obtain a new identity for the quark–gluon interaction vertex based on gauge symmetry, which is similar to the Slavnov–Taylor Identities (STIs) based on the Becchi–Rouet–Stora–Tyutin transformation. With these identities, we find that in Landau gauge, the dressing function of the ghost propagator approaches to a constant as its momentum goes to zero, which provides a strong constraint on the infrared behaviour of ghost propagator.
