The physical states of QCD

Published

Journal Article (Academic article)

We use the constraint imposed by Gauss's law to argue that the color charged states of SU(3) [quantum chromodynamics (QCD)] are not physical. We further show that the matrix elements of products of gluon field and quark current operators at different space-time points vanish when taken between physical states. This is true even if the operators are combined to make up color singlet objects. These results are in keeping with experimental observation
