摘要：We discuss a proposal for the construction of lattice QCD with gauge action, fermionic action,
q–term, and the operators all based on the lattice Dirac operator D with exact chiral symmetry.
The simplest regularization of this type uses the proposition that the classical limit of scalar gauge
density associated with trace of D is (up to an additive constant) proportional to trF2, while the
corresponding operator is local. More general formulations from this class are considered with the
aim of exposing interrelations between gauge and fermionic aspects of QCD which are otherwise
hidden in generic formulations. Possible utility of these formulations for exploring QCD vacuum
structure is emphasized.
