Non-perturbative propagators and dimension 2 condensate in Yang-Mills theory

Abstract

Various condensates are related to nonperturbative properties of QCD. The importance of the condensates such as 〈FF 〉 and 〈q̄q〉 are wellknown. Though the dimension two operators such as mass terms are not BRST invariant in Yang-Mills (YM) theory, it was pointed out recently that these operators contain a gauge invariant physical part and that a special… (More)
