The heavy quarks are one of the most versatile probes of the strongly coupled QCD medium created in the heavy ion collision experiments. However, the interactions of the heavy quarks or heavy quark bound states with the strongly coupled medium is still not well understood. One of the ways to look at such interactions is to study the behaviour of open charm hadrons in the thermalized...

PHENIX has measured single electrons from charm and bottom decays at midrapidity in Au+Au collisions at $\sqrt{s_{NN}}$=200 GeV. Previous heavy-flavor electron measurements have indicated substantial modification of the momentum distribution of the parent heavy-flavor hadrons. Using the PHENIX barrel silicon-vertex tracker (VTX) to measure displaced vertices precisely, the...

The mass of charm quarks is larger than the scales of the medium created in heavy­-ion collisions at RHIC energies (m_c >> Λ_QCD, T, m_u,d,s ). Therefore, charm production is mainly feasible in the primordial nucleon-­nucleon collisions and experience all the subsequent stages of the medium evolution. The modification of charm quark production in heavy -ion...

Heavy quarks, i.e. charm and beauty, are sensitive probes of the medium produced in high-energy heavy-ion collisions. They are produced in the early stage of the collisions and are expected to experience the whole history of the collision evolution interacting with the medium constituents via both elastic and inelastic processes. The nuclear modification factor ($R_{\rm AA}$) and...

692. Beauty production in heavy ion collisions with CMS

Contributed talk

The study of beauty production in heavy-ion collisions is considered one of the key measurement to address the flavour-dependence of in-medium energy loss in PbPb collisions. In pPb collisions, studies of b-quark production can also provide insights into the relevance of cold nuclear matter effects in the heavy-flavour sector. The CMS experiment has excellent capabilities for measuring b-quark...

Heavy mesons are one of the few probes which allow for studying the properties of a plasma of quarks and gluons (QGP) created in ultra-relativistic heavy ion collisions. To do this we have to follow the heavy quarks from their production point through the QGP up to the final rescattering of heavy mesons with hadrons after the hadronization. The interaction of heavy quarks in the QPG is...
