Query: Dirac Quantization of Restricted QCD   We discuss the quantization of the restricted gauge theory of SU(2) QCD
regarding it as a second-class constraint system, and construct the BRST
symmetry of the constrained system in the framework of the improved Dirac
quantization scheme. Our analysis tells that one could quantize the restricted
QCD as if it is a first-class constraint system.
