Title: First Measurement of $Λ_{c}$ Baryon Production in $Au + Au$ Collisions at $\sqrt{s_{N N}} = 200 GeV$

Herein we report on the first measurement of the charmed baryon $Λ_{c}^{\pm}$ production at midrapidity ( $| y | < 1$ ) in $Au + Au$ collisions at $\sqrt{s_{NN}} = 200 GeV$ collected by the STAR experiment at the Relativistic Heavy Ion Collider. The $Λ_{c} / D^{0}$ [denoting $(Λ_{c}^{+} + Λ_{c}^{-}) / (D^{0} + {\bar{D}}^{0})$ ] yield ratio is measured to be $1.08 \pm 0.16 (stat) \pm 0.26 (sys)$ in the 0%–20% most central $Au + Au$ collisions for the transverse momentum ( $p_{T}$ ) range $3 < p_{T} < 6 GeV / c$ . This is significantly larger than the pythia model calculations for $p + p$ collisions. The measured $Λ_{c} / D^{0}$ ratio, as a function of $p_{T}$ and collision centrality, is comparable to the baryon-to-meson ratios for light and strange hadrons in $Au + Au$ collisions. Model calculations including coalescence hadronization for charmed baryon and meson formation reproduce the features of our measured $Λ_{c} / D^{0}$ ratio.
