Λ and Σ potentials in dense matter based on chiral EFT: Bridging heavy-ion collisions, hypernuclei, and neutron stars
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.
