Constructing local composite operators for glueball states from a confining Gribov propagator

M. A. L. Capri, A. J. Gomez, M. S. Guimaraes +3

The construction of BRST invariant local operators with the quantum numbers of the lightest glueball states, $J^{PC}=0^{++},2^{++},0^{-+}$, is worked out by making use of an Euc…
