Key Points

This research aims to explore how Λ and Σ hyperon single-particle potentials influence directed flow in heavy-ion collisions.
Analyzed A and E directed flows at √sNN = 4.5 GeV.
Used G-matrix calculations incorporating two- and three-body forces from SU(3) chiral effective field theory.
Investigated the sensitivity of flows to variations in single-particle potentials.
Λ + Σ0 directed flow shows sensitivity to changes in the Σ single-particle potential.
More pronounced effects observed for Σ0 directed flow compared to others.
Findings suggest important connections to hypernuclei and neutron stars.

Abstract

The A and E directed flows at √sNN = 4.5 GeV are investigated to examine their sensitivity to the hyperon single-particle potentials. The single-particle potentials are obtained from G-matrix calculations with two- and three-body forces based on SU(3) chiral effective field theory. The Λ + Σ0 directed flow shows sensitivity to the variation in the Σ single-particle potential. Its effect is more pronounced for the Σ0 directed flow.
