Measurement of heavy-flavour production, correlations and jets with ALICE / Sakai, Shingo (Tsukuba U., GSPAS) /ALICE Collaboration
In this article, recent ALICE measurements of the RAA and v2 of electrons at mid-rapidity (|y|<0.6) and muons at forward rapidity (2.5<y<4), from semi-leptonic decays of heavy-flavour hadrons in Pb–Pb collisions at = 5.02 TeV are shown. The results of D-tagged jet production cross-section in pp collisions at $\sqrt{s_{NN}}$ =7 TeV are presented. [...]

UPC: a powerful tool for ${\mathrm J}/\psi$ photoproduction analysis in ALICE / Ragoni, Simone (Birmingham U.)
Ultra-peripheral collisions (UPC) occur when the interacting nuclei or protons have an impact parameter larger than the sum of their radii. [...]

Jet acoplanarity via hadron+jet measurements in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV with ALICE / Norman, Jaime (Liverpool U.)
We present the first fully-corrected semi-inclusive distribution of charged jets recoiling from a trigger hadron in 0-10% Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV as a function of the azimuthal angle between the trigger hadron and jet, $\Delta\varphi$. [...]

Measurement of Jet Modification through Jet-hadron Correlation in Pb–Pb Collisions at $\sqrt{s_{\text{NN}}} = 5.02$ TeV / Hosokawa, Ritsuya (Tsukuba U. (main) ; LPSC, Grenoble) /ALICE Collaboration
Jets are well calibrated and established probes of the properties of Quark-Gluon Plasma (QGP), which is hot and dense QCD medium formed in relativistic heavy-ion collisions. At the formation of QGP, initial energies of the hard scattered partons, which are the origin of jets, can be suppressed and re-distributed while traversing the QGP. [...]

Quarkonium Production in pp, pA, and AA Collisions / Hayashi, ShinIchi (Tokyo U., CNS, Saitama) /ALICE Collaboration
Quarkonium production is studied in pp, p–Pb, Pb–Pb and Xe–Xe collisions using the ALICE detector at the CERN LHC. In p–Pb collisions, a differential J/$\psi$ with respect to transverse momentum, rapidity, and collision centrality is performed and the results can be described by theoretical calculations including cold nuclear matter effects except at backward rapidity.

Measurement of the neutral and charged K* (892) mesons in the MPD experiment at NICA / Ivanishchev, Dmitry (St. Petersburg, INP) ; Kotov, Dmitry (St. Petersburg, INP ; St. Petersburg Polytechnic Inst.) ; Kryshen, Evgeny (St. Petersburg, INP) ; Malaev, Mikhail (St. Petersburg, INP) ; Riabov, Victor (St. Petersburg, INP ; Moscow Phys. Eng. Inst.) ; Ryabov, Yuriy (St. Petersburg, INP) /ALICE Collaboration ; MPD Collaboration
Measurements of K*(892) meson production provide the means to study properties of relativistic heavy-ion collisions. Because of their short lifetimes, the charged and neutral K*(892) mesons provide information about the properties of the late hadronic phase due to the presence of rescattering and regeneration effects that can modify resonance yields.

Production of $\Sigma^0$ Hyperons at LHC with ALICE / Borissov, Alexander (Moscow, MIPT) /ALICE Collaboration
The first measurements of the transverse momentum ($p_T$) spectra and integrated yields of $\Sigma^0$ and $\overline{\Sigma}^0$ baryons in proton-proton (pp) collisions at $\sqrt{s}$ = 7 TeV are reported. The $\Sigma^0$ ($\overline{\Sigma}^0$) signal is reconstructed via the $\Lambda$ ($\overline{\Lambda}$) + $\gamma$ decay channel by invariant mass analysis. [...]
