Abstract

In this work, the study of azimuthal anisotropy in O–O collisions at LHC energies is performed using the HYDJET++ Monte Carlo event generator. While most investigations have traditionally focused on large nuclear systems such as Pb–Pb or Xe–Xe collisions, recent experimental programs at the LHC have highlighted the importance of exploring smaller ones, such as O–O and Ne–Ne. Here, we investigate various methods for calculating azimuthal flows, including the true reaction plane method, multiparticle cumulants, and the scalar product method. The applicability and limitations of these approaches in small nuclear systems are discussed, with particular emphasis on their differences from heavy-ion collisions. The obtained results provide useful insights into the potential of hybrid Monte Carlo generators for studies of small nuclear systems at extreme energies.
