Open and hidden heavy-flavor physics in high-energy nuclear collisions are entering a new exciting stage towards reaching clearer understanding of the experimental results with possibility to link them directly advancement lattice Quantum Chromo-Dynamics (QCD). Recent from experiments theoretical developments regarding open dynamics have been debated at Lorentz Workshop Tomography Quark-Gluon Plasma Heavy Quarks, which was held October 2016 Leiden, The Netherlands.

With a HERMES-like hydrogen polarised target, such measurements over year can reach precisions close per cent level. This is particularly remarkable since these analyses probably not be carried out anywhere else
