Jets including heavy flavor quarks (HF-jets) are mostly produced from initial hard scattering in relativistic heavy ion collisions. Therefore it is a good probe to study the properties of quark gluon plasma produced from heavy ion collisions. Jets initiating from bottom quarks ($b$-jets) can be identified by the characteristic of b-hadrons such as long lifetime and heavy mass. sPHENIX...

In heavy-ion collisions, quarkonium states are used to study the properties of the quark-gluon plasma. Measurements of quarkonia in p+p collisions serve as important references. However, the production mechanism of quarkonium states in p+p collisions is still not fully understood because it involves both perturbative and non-perturbative QCD processes. Measurements of $J/\psi$ production with...

Measurements of open-charm hadrons in ultra-relativistic heavy-ion collisions are an important part of the heavy-ion physics program of the STAR experiment. The charm quarks can be used to study the properties of the Quark-Gluon Plasma (QGP) as they are produced predominantly in hard partonic scatterings at the very early stage of heavy-ion collisions which means that they experience the whole...

In low energy heavy-ion collisions, directed and elliptic flow, $v_1$ and $v_2$, are sensitive to the dynamics at the early stage of the system evolution and equation of state of the medium. The triangular flow $v_{3}$ provides complementary information on the initial geometry fluctuations and transport properties of the medium. The hadronic interaction cross sections of multi-strange hadrons...

Quark-gluon plasma (QGP) is an interacting localized assembly of quarks and gluons at thermal and chemical equilibrium at extremely high temperature or density. It is believed that the suppressed J/$\psi$ production in relativistic heavy-ion collisions is one of the important experimental observations for the production of the QGP. However, in order to correctly interpret those results, the...

The dynamics of shower development for a jet traveling through the quark-gluon plasma (QGP) involves a variety of scales, including the mass for heavy flavors in jets. During the high virtuality portion of the jet evolution, the mass of the heavy quark affects longitudinal drag and diffusion, stimulating additional radiation. These emissions partially compensate the reduction in radiation from...

Bottomonium states are key probes for experimental studies of the quark-gluon plasma (QGP) created in high-energy nuclear collisions. Theoretical models of bottomonium productions in high-energy nuclear collisions rely on the in-medium interactions between the bottom and antibottom quarks. The latter can be characterized by the temperature ($T$) dependent potential, with real ($V_R(T,r)$) and...

The measurement of relative production rates of different charm hadrons allows us to study hadronization mechanisms of charm quarks and to investigate different hadronization models. Various hypotheses are inspected like recombination, colour reconnection and decay from unknown excited states.
The results discussed in this contribution provide the first $\Sigma_{c}^{0,++}$ production...

Exciting experimental results on the flow of charmonia and bottomonia with an unprecedented level of precision pose the important physics question about the possible heavy-quark thermalization in the quark-gluon plasma (QGP). In this work, a new hydrodynamic approach to the transport of heavy quarks in the QGP is presented. We exploit the conservation of the number of heavy quark-antiquark...

The deconfined quark-gluon plasma (QGP) created in relativistic heavy-ion collisions is not only a perfect fluid with very small $\eta/s$ but also a most "charming" system with hundreds of charm quarks. Meanwhile, it is widely accepted that the quark hadronization mechanism changes with the appearance of QGP. The production of charmed hadrons differs significantly in $A$-$A$ collisions from...
