Open charm production and ${\Lambda }_c^{+}/D^0$ ratio in pp and Au+Au collisions at the RHIC

Bijun Fan, Chao Zhang, Liang Zheng +1

We study open charm hadrons production in pp and Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}=200$~GeV using an improved a multi-phase transport (AMPT) model. Specifically, we sho…
