Specifically, we use the JAM transport model in which potentials are implemented based on the framework of the relativistic quantum molecular dynamics. Our approach reproduces the rapidity dependence of directed flow data up to $\\sqrt{s_{NN}}\\approx 8$ GeV showing the significant importance of mean-field.
