Query: Large distance behaviour of light cone operator product in perturbative
  and nonperturbative QCD regimes   We evaluate the coordinate space dependence of the matrix elements of the
commutator of the electromagnetic and gluon currents in the vicinity of the
light-cone but at large distances within the parton model, DGLAP, the
resummation approaches to the small x behaviour of DIS processes, and for the
Unitarity Bound. We find that an increase of the commutator with relative
distance $py$ as $\propto (py)f(py,y^2=t^2-r^2)$ is the generic property of QCD
at small but fixed space-time interval $y^2=t^2-r^2$ in perturbative and
nonperturbative QCD regimes. We explain that the factor $py$ follows within the
dipole model (QCD factorization theorem) from the properties of Lorents
transformation. The increase of $f(r)$ disappeares at central impact parameters
if cross section of DIS may achieve the Unitarity Limit. We argue that such
long range forces are hardly consistent with thermodynamic equilibrium while a
Unitarity Limit may signal equilibration. Possible implications of this new
long range interaction are briefly discussed.
