Heavy quarks are valuable probes of the dense nuclear matter produced in relativistic heavy-ion collisions. We establish a comprehensive framework that describes their entire temporal evolution in the QGP matter and the subsequent hadron gas. The dynamics of open heavy quarks in the QGP is described using either an improved Langevin approach [1,2] or a linearized Boltzmann approach [3] that...

Heavy quarks are considered as an excellent probe for the early dynamics in heavy-ion collisions. Among all open charm mesons, $D_{s}^{+}(c\bar s)$ and $D_{s}^{-}(\bar c s)$ mesons play a unique role to quantify heavy quark diffusion and hadronization in heavy-ion collisions, because of their valence quark compositions. Also, like multi-strange hadrons, $D_{s}^{\pm}$ mesons are...

Heavy flavor quarks are suggested as excellent probes to study the strongly interacting Quark-Gluon Plasma (QGP) discovered in high-energy heavy-ion collisions. Measurements of heavy flavor production will advance our understanding of the properties of the QGP. Studies in different heavy-ion collision systems and centralities, and separately for charm and bottom quarks can provide new insights...

PHENIX installed and commissioned a forward silicon vertex tracker (FVTX) in 2012. The complete detector covers the rapidity range of $1.2 < |y| < 2.2$, and each arm has full azimuthal coverage. This acceptance matches that of the PHENIX muon arms. With the barrel silicon vertex detector, the FVTX greatly improves tracking to the collision vertex, and is able to identify secondary...

The ATLAS measurement of the nuclear modification factor (RAA) and the elliptic flow (v2) of muons from heavy quark decays in Pb+Pb collisions at sqrt(s_NN)= 2.76 TeV are presented. The measurements are done over the pT range of 4-14 GeV and over the centrality range of (0-60)% within pseudorapidity interval of |η|<1.  A significant elliptic flow is observed over the full pT range for all...
