Open and hidden heavy-flavor production and flow in Heavy Ion Collisions.

Their fast formation and microscopic scale of heavy flavor (HF) probes are ideal for a Quark-Gluon Plasma (QGP) tomography. Besides, the large fraction of energy carried by the measured heavy flavor hadron from the hard process fragmentation also favors a precise study of the partonic density and initial state effects in nucleus. LHC experiments are exploring heavy flavor probes in different manners such as the study of partonic energy loss in cold and QGP medium, diffusion properties, hadron coalescence and local free energy quantification using bound state quarkonia. This manuscript summarizes the most recent experimental developments in the field coming from all LHC experiments using data taken in $p$Pb and PbPb collisions in collision energies ranging from 86.6 GeV to 8.16 TeV.
