A phenomenological approach to direct ${\mathrm{K}}^{\ast }$ production and hadronic medium effects in nucleus-nucleus collisions at high baryon density

Hongcan Li, Yun Liu, Guangyu Zheng +3

Short-lived hadron resonances serve as sensitive probes of the late-stage hadronic medium in heavy-ion collisions. Using the AMPT-HC model, we study ${\mathrm{K}}^{\ast }(892)$ production…
