The hypothesis of the relation between strong azimuthal correlations, known as alignment, in families of hadrons and photons observed in cosmic ray experiments and the selection procedure of the highest-energy particles together with the transverse momentum conservation are tested in the framework of the HYDJET++ model. The results show that the high degree of alignment can appear in nucleus-nucleus interactions at reasonable values of the transverse momentum disbalance of most energetic detected particles.
