Abstract

We discuss how the presence of a squeezed gluon vacuum might lead to quarkconfinement in the framework of the global color model of QCD. Using reduced phase space quantization of massive vector theory we construct a Lorentz-invariant and colorless squeezed gluon condensate and show that it inducesa permanent, nonlocal quark interaction (delta-function in four-momentum space), which according to Munczek and Nemirovsky might lead to quark confinement. Our approach makes it possible to relate the strength of this effective confining quark interaction to the strength of the physical gluon condensate.
