“…We present results on top quark and on the pairs of top and anti-top quarks, that are expected to be mostly produced through gluon fusion at the LHC. The top mass is determined by making use of a template methods in the single-lepton and all-hadronic channels. …”

“…The ALICE experiment studies the properties of the strongly-interacting matter created in high energy heavy-ion collisions, called Quark-Gluon Plasma (QGP). Heavy quarks are a powerful probe for investi- gating such a state of matter, since they are predominantly produced in the first hard scattering processes and they bring to the final state information on the deconfined phase. …”
