Heavy quarks are initially produced in nuclear collisions and the number is conserved during the evolution of the system. We establish a sequential coalescence model with charm conservation and apply it to charmed hadron production at RHIC and LHC energies. The charm conservation enhances the earlier formed hadrons and reduces the later formed ones, which leads to a Ds/D0 enhancement and a...
Due to their large masses, the interactions of heavy quarks with the quark-gluon plasma (QGP) may be different from those of light quarks. The lightest charm baryon is the $\Lambda_{c}^{+}$, composed of a charm quark and two light quarks. Measurements of $\Lambda_{c}^{+}$ production in both pp and PbPb collisions can provide important inputs to the understanding of heavy quark transport in the...
Starting from the investigation on recent experiments about charmed hadrons, e.g., nuclear modification factor ratios between charmoinum states and measurements of doubly charmed hadrons, we discuss the production of those charmed hadrons by recombination in heavy ion collisions. We adopt the coalescence model, and evaluate transverse momentum distributions of not only charmonium states but...
The hadronization process of heavy hadrons with bottom and charm quarks, especially for baryons $\Lambda_c$ and $\Lambda_b$, in a dense QGP medium is largely not understood.
We present predictions obtained with a coalescence plus fragmentation model, for $D^0$, $D_s$, $\Lambda_c$, B and $\Lambda_b$ spectra, the related baryon to meson ratios and the $D_s/D^0$ ratio, both at RHIC and LHC...
Charm quarks are a powerful probe of the Quark-Gluon Plasma (QGP) formed in high energy heavy-ion collisions. Produced in hard scattering processes on a timescale shorter than the QGP formation time, they experience the whole system evolution. There have been extensive researches regarding the production of charm mesons, such as D$^0$, D$^+$, D$^{*+}$, in heavy-ion collisions to investigate...
We present high statistics data on proton and light nuclei emission from Au+Au collisions at $\sqrt{s_{NN}}$ = 2.4 GeV measured with HADES.
The data are analysed as function of reduced transverse mass $m_t - m_0$ and rapidity $y$ in 4 centrality classes corresponding to the 40$\%$ most central events.
In contrast to higher energies light nuclei are not rare but make up about 30$\%$ of all...
The high energy pp, p-Pb, and Pb-Pb collisions at the LHC offer a unique tool to study the production of light (anti-)nuclei. The study of the production yield of (anti-)nuclei in heavy-ion collisions at the LHC energy probes the late stages in the evolution of the hot, dense nuclear matter created in the collision and serves as baseline for the search of exotic multi-baryon states.
