Unraveling alignment pattern in high-energy particles via transverse momentum disbalance analysis

Abstract

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.
