Measurements of open heavy flavour mesons can be used to study the proprieties of the, so called, quark-gluon plasma produced in heavy-ion (A+A) collisions. The STAR collaboration searches for differences in particle production between the A+A and p+p collisions via the nuclear modification factor. In the low-pt region, ${\rm D^{\pm}}$ mesons cannot be directly reconstructed with traditional...

Měřením produkce mezonů D$^{\pm}$ v ultra-relativistických jádro-jádrových srážkách se studují vlastnosti kvark-glounového plazmatu (QGP). Půvabné kvarky v těchto mezonech totiž vznikají ještě před zažehnutím QGP v tzv. tvrdých procesech a musí tedy projít část objemu QGP, kde ztratí část své hybnosti a energie. Tyto ztráty lze kvantifikovat srovnáním produkce D$^{\pm}$ v jádro-jádrových a...

48. The effects of QGP and CNM on heavy quarkonia production

Oliver Matonoha (CTU FNSPE)

In this presentation, we will give an introduction to the physics of heavy quarkonia in ultra-relativistic collisions of heavy nuclei. Different production-affecting phenomena will be overviewed and juxtaposed with experimental results of related observables. Furthermore, we will present recent measurements of the $\Upsilon$ production in Au+Au collisions at $\sqrt{s_\mathrm{NN}}=200$~GeV via...

45. $\Lambda_\mathrm{c}$ baryon reconstruction and measurement of the $\overline{\Lambda_\mathrm{c}}^- / \Lambda_\mathrm{c}^+$ at the STAR detector in Au+Au collisions at $\sqrt{s_\mathrm{NN}}$ = 200 GeV

$\Lambda_\mathrm{c}$ is the lightest baryon containing a charm quark and, as such, presents a unique probe into the bahavior of heavy quarks in the hot and dense QCD medium. Together with the measurement of the D$^0$ meson, we can probe the various modes of hadronization of the charm quark in heavy-ion collisions and bring more insight into the possible process of quark coalescense in the...
