The lowest anomalous dimension is separated from the remaining, continuous, spectrum by a finite gap. The corresponding eigenfunction coincides with the contribution of quark-gluon states to the two-particle DA $\\phi_-(\\omega)$ so that the evolution equation for the latter is the same as for the leading-twist DA $\\phi_+(\\omega)$ up to a constant shift in the anomalous dimension.
