Abstract
In the double logarithmic approximation of perturbative QCD we show th at the anomalous dimension of the four-gluon operator in DIS has a ric h analytic structure. In addition to a pole on the physical sheet we f ind singularities on second and other nonphysical sheets. We attempt t o interpret these singularities as bound states' and resonances.
