Abstract
The hypothesis of the factorization of the double nuclear
modification factor in relativistic heavy ion collisions is tested for
different types of final-state hadrons within the HYDJET++ model. The
results demonstrate that this factorization holds reasonably well at
moderately high transverse momenta, provided that the effects of double
parton scattering can be small or neglected.
