D-meson nuclear modification factor and elliptic flow measurements in Pb–Pb collisions at $\sqrt {s_{NN}}$ = 5.02TeV with ALICE at the LHC / Barbano, Anastasia (INFN, Turin ; Turin U.) /ALICE
ALICE measured the nuclear modification factor ($R_{AA}$) and elliptic flow ($\nu_{2}$) of D mesons ($D^{0}$, $D^{+}$, $D^{⁎+}$ and $D^{s+}$) in semi-central Pb–Pb collisions at $\sqrt{s_{NN}} =5.02$ TeV. The increased amount of data in semi-central Pb–Pb events obtained with the LHC Run 2 provides access to more precise measurements for the $R_{AA}$ and the non-strange D-meson $\nu_{2}$ with respect to Run 1 results, as well as to the first measurement of the $D_{s}$ -meson $\nu_{2}$ at LHC energies.

Direct photon measurements in pp and Pb–Pb collisions with the ALICE experiment / Germain, M (SUBATECH, Nantes) /ALICE
Direct photon production in heavy-ion collisions provides a valuable set of observables to study the hot QCD medium. The direct photons are produced at different stages of the collision and escape the medium unaffected. [...]

Highlights of experimental results from ALICE / Timmins, Anthony (Houston U.) /ALICE
Highlights of recent results from the ALICE collaboration are presented. The collision systems investigated are Pb–Pb, p–Pb, and pp, and results from studies of bulk particle production, azimuthal correlations, open and hidden heavy flavor, and hard probes are shown. [...]

Noncommutative Black Holes at the LHC / Villhauer, Elena Michelle (CERN)
Based on the latest public results, 13 TeV data from the Large Hadron Collider at CERN has not indicated any evidence of hitherto tested models of quantum black holes, semiclassical black holes, or string balls. Such models have predicted signatures of particles with high transverse momenta. [...]

Jet-hadron correlations relative to the event plane at the LHC with ALICE / Mazer, Joel (Tennessee U.) /ALICE
In ultra relativistic heavy-ion collisions at the Large Hadron Collider (LHC), conditions are met to produce a hot, dense and strongly interacting medium known as the Quark Gluon Plasma (QGP). Quarks and gluons from incoming nuclei collide to produce partons at high momenta early in the collisions. [...]

ALICE measurement of the $J/\psi$ nuclear modification factor at mid-rapidity in Pb–Pb collisions at $\sqrt{{s}_{NN}}=$ 5.02 TeV / Jiménez Bustamante, Raúl Tonatiuh (Heidelberg Observ. ; Darmstadt, GSI) /ALICE
ALICE at the LHC provides unique capabilities to study charmonium production at low transverse momenta ( p T ). At central rapidity, ( |y|<0.8 ), ALICE can reconstruct J/ ψ via their decay into two electrons down to zero p T . [...]

New high resolution measurements of open and hidden charm production in proton-nucleus collisions at $\sqrt{s}=110$ GeV with LHCb / Maurice, Émilie (Ecole Polytechnique) /LHCb
Open and hidden charm production in nucleus-nucleus collisions is considered as a key probe of Quark Gluon Plasma (QGP) formation. In the search of specific QGP effects, proton-nucleus collisions are used as the reference as they account for the corresponding Cold Nuclear Matter (CNM) effects. [...]

Electroweak boson production in p–Pb and Pb–Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV with ALICE / Stocco, Diego (SUBATECH, Nantes) /ALICE
W and Z bosons are massive weakly-interacting particles, insensitive to the strong interaction. They provide therefore a medium-blind probe of the initial state of the heavy-ion collisions. [...]

Investigations of anisotropic collectivity using multi-particle correlations in pp, p–Pb and Pb–Pb collisions / Gajdošová, Katarína (Bohr Inst.) /ALICE
Two- and multi-particle azimuthal correlations have proven to be an excellent tool to probe the properties of the strongly interacting matter created in heavy-ion collisions. Recently, the results obtained for multi-particle cumulants have been interpreted as evidence for collectivity in the small collision systems (pp and p–Pb) providing new insights into the systems' fluctuating initial conditions.
