A universal constraint on the infrared behavior of the ghost propagator in QCD
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....
