“…The azimuthal anisotropies of particle yields observed in relativistic heavy-ion collisions are considered as an evidence of the formation on a deconfined Quark-Gluon Plasma produced in these collisions. Interestingly, recent measurements in $pp$ and $p$+Pb systems from ATLAS and other experiments show similar features as those observed in A+A collisions, indicating the possibility of the production of such a deconfined medium in smaller collision systems. …”

“…Measurements in pp and p-Pb collisions also provide a baseline for Pb-Pb collisions, where the baryon-to-meson ratios will offer a unique probe of charm thermalisation and hadronisation mechanisms in the Quark-Gluon Plasma.</p> <p>The production of D0, D+, D*+ and Ds mesons has been measured with ALICE in pp collisions at the LHC at several collision energies, and was found to be compatible with expectations from theory. …”

“…While theoretical calculations incorporating partonic energy loss in the quark gluon plasma can successfully describe the measured $\mathrm{B\rightarrow{D^0}}$ suppression at higher $p_{\rm{T}}$, the data show an indication of larger suppression than the model predictions in the range of $2 < p_{T} < 5$ ${\rm Ge\hspace{-.08em}V\hspace{-0.16em}}/\hspace{-0.08em}c$.…”

“…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. …”
