“…Presented measurements of muon pairs produced via two-photon scattering processes in hadronic Pb+Pb collisions provide a novel test of strong-field QED by exploiting correlations between the lepton pair and second-order event-plane, which can potentially be a sensitive electromagnetic probe of the quark-gluon plasma. Results are compared with recent theory calculations.…”

“…These include measurements of $v_n-[p_\mathrm{T}]$ correlations in Xe+Xe and Pb+Pb, which carry important information about the initial-state geometry of the Quark-Gluon Plasma and can potentially shed light on any quadrupole deformation in the Xe nucleus; measurements of flow decorrelations differential in rapidity, which probe the longitudinal structure of the colliding system; and measurements of the sensitivity of collective behavior in $pp$ collisions to the presence of jets, which seek to distinguish the role that semi-hard processes play in the origin of these phenomena in small systems. …”

“…The main goal of the experiment is to observe and study the phase transition from hadronic matter to deconfined partonic matter (Quark Gluon Plasma &#8212; QGP). ALICE is conceived as a general purpose detector and will address most of the phenomena related to the QGP formation at LHC energies: to this purpose, a large fraction of the hadrons, leptons and photons produced in each interaction will be measured and identified.…”
