  The azimutal correlations of heavy quarks produced in the high energy $pp$
($p\bar{p}$) collisions are calculated in the framework of QCD without the
usual assumptions of the parton model. The virtual nature of the interacting
gluons as well as their transverse motion and different polarizations are taken
into account. We give some predictions for the azimutal correlations of charm
and beauty hadrons produced at Tevatron-collider and LHC.
