$D^0$-$D_s^{+}$ Elliptic-Flow Splitting under Event-Shape Engineering: A Probe of Sequential Charm Hadronization

Yu-Jie Huang, Wei Dai, Jiaxing Zhao +3

Recent work has proposed sequential hadronization of open-charm hadrons in the quark-gluon plasma, wherein more tightly bound species such as $D_s^{+}$ form earlier near $1.2T_c$ an…
