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. In this contribution, we...
Excitation functions for sub- and near-barrier total (complete + incomplete) fusion cross sections are presented the 6,7Li+59Co reactions. Evaporation residues were identified by their characteristic γ rays corresponding yields measured with both IReS Garel array at Vivitron facility São Paulo Ge 8UD Pelletron tandem using standard γ-ray techniques.
