“…The study of the production of charm quarks in high-energy atomic-nucleus collisions offers an genuine approach for the study of the quark-gluon plasma. The understanding and characterisation of this state of deconfined-matter, at first sight created in heaviest systems, require a fine knowledge of lightest systems, such as proton-proton (pp) and proton-lead (p-Pb) collisions. …”

“…--HTML--><p><span style="color:#000000">In collisions of ultra-relativistic heavy nuclei, the matter undergoes a phase transition into a deconfined state, known as Quark-Gluon Plasma (QGP). The QGP behaves as an almost perfect fluid, transforming the spatial anisotropies of the initial collision geometry into final-state particle momentum anisotropies, called anisotropic particle flow. …”

“…The ATLAS W and Z boson data exhibit sensitivity to the valence quark distributions and the light quark sea composition, whereas the top-quark pair production data have sensitivity to the gluon distribution. The impact of the top-antitop production data is increased by fitting several distributions simultaneously, with the full information on the systematic and statistical correlations between data points. …”

“…The average jet charge, defined as the momentum-weighted sum of the electric charges of particles inside the jet, is a proxy of the electric charge of the quark or gluon that initiates the jet. We demonstrate how the factorization framework of soft-collinear effective theory can be generalized to evaluate the jet charge in a dense strongly-interacting matter environment, such as the one produced in nuclear reactions at collider energies. …”
