In this presentation, the properties of Upsilon mesons are going to be discussed. These mesons can be used to probe the quark-gluon plasma (QGP) created in A+A collisions. In particular, the Upsilon suppression mechanism in the presence of QGP will be described. Recent results of Upsilon suppression measurements in Au+Au collisions from the STAR experiment will be shown. Next, the experimental...

Studies of $J/\psi$ and $\Upsilon$ production provide insight into quarkonium production mechanism and allow to test QCD. Furthermore, studies of quarkonium suppression in heavy-ion collisions relative to p+p collisions can provide information about the properties of quark-gluon plasma(QGP) created in these collisions.

KF Particle Finder založený na balíčku KF Particle se používá k rekonstrukci krátce žijících částic pomocí kombinování trajektorií jejich dcer. Balíček využívá algoritmus nazývaný Kálmánův filtr a navržen byl původně pro experiment CBM v laboratoři FAIR za účelem online rekonstrukce částic. Pomocí KF Particle Finder lze trajektorie zkoumat společně s jejich chybami. Odchylky trajektorií částic...

Charm quarks are primarily produced at early stages of ultra-relativistic heavy-ion collisions and can therefore probe the Quark-Gluon Plasma (QGP) throughout its whole evolution. Final-state open-charm hadrons are commonly used to experimentally study the charm quark interaction with the QGP. Thanks to the precise secondary vertex reconstruction provided by the Heavy Flavor Tracker (HFT),...

Charm quarks, which are created during first moments of ultrarelativistic heavy-ion collisions, serve as a probe inside the Quark-Gluon Plasma. Measurements of the production of open-charmed mesons, such as D$^\pm$, can provide us with an insight to the interaction of charmed quarks inside the strongly interacting medium. The results from STAR measurements, which have been enabled by the...

An azimuthal anisotropy of produced particles ($v_2$) has been observed in small-system collisions of high multiplicities. To better understand its origin, it is important to study charm quark azimuthal anisotropy in these systems. The analysis of $v_2$ of open charm meson D$^0$ from d+Au collisions at 200 GeV with the STAR experiment will be presented.

The STAR experiment at the Relativistic Heavy Ion Collider performs studies of diffractive processes with the focus on the exclusive production of particles in central range of rapidity. In 2017, STAR collected measured proton-proton collisions at $\sqrt{\mathsf{s}} = 510$ GeV to study Central Exclusive Production process $pp \ \rightarrow \ pXp$ through Double Pomeron Exchange mechanism. The...
