Directed flow of $\Lambda$ in high-energy heavy-ion collisions and $\Lambda$ potential in dense nuclear matter

Yasushi Nara, Asanosuke Jinno, Koichi Murase +1

We investigate the sensitivity of the $\Lambda$ directed flow to the $\Lambda$ potential in mid-central Au + Au collisions at $\sqrt{s_{NN}}\approx 3.0$--$30$ GeV. The $\Lambda$ potential obtained fr…
