Collective Flow Harmonics Correlations at the NICA Energy Range

A primary objective of beam energy scan using heavy-ion collisions is to explore the high-density matter equation of state (EoS) and potential phase transitions. Anisotropic flow measurements, defined from the azimuthal distributions of final-state charged particles, offer a powerful tool to extract such information. The correlations between different flow harmonics can impose even stronger constraints on the EoS parameters and provide further understanding of the underlying flow formation dynamics. This study investigates the correlations among the directed flow ( $${{v}_{1}}$$ ), elliptic flow ( $${{v}_{2}}$$ ), and triangular flow ( $${{v}_{3}}$$ ) using a state-of-the-art heavy-ion collision model JAM for the Nuclotron–NICA energy range. The model’s predictions are compared with the available data from the HADES experiment.
