Description

We calculate the gluon structure function of a color dipole in a new approach evaluating the matrix element of gluon field operators separated along a direction close to the light cone. As vacuum state in the pure glue sector, we use a variational ground state of the near-light-cone Hamiltonian. With a mean momentum fraction of the gluons fixed to the ''experimental value'' in a proton, the resulting gluon structure function for a dipole state with four links is rather close to the NLO MRST 2002 and the CTEQAB-0 parameterizations at Q2=1.5 GeV2.
