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. [...]

Direct photon production in pp, p-Pb and Pb-Pb collisions: results from ALICE / Blau, Dmitry (Kurchatov Inst., Moscow) /ALICE Collaboration
Direct photon measurements provide a tool for testing QCD predictions in pp collisions and valuable information about properties of the quarkgluon matter created in nucleus-nucleus collisions. Comparing direct photon production in pp, p-Pb and Pb-Pb collisions, one can check the scaling with the number of binary collisions expected at high transverse momentum and get insight into the hot and cold hadronic matter properties with soft photons.

Overview of hard hadron production results in ALICE / Peresunko, Dmitri (Kurchatov Inst., Moscow) /ALICE Collaboration
The ALICE experiment is designed to study the properties the hot and dense medium, the Quark-Gluon Plasma (QGP), produced in ultrarelativistic heavy-ion collisions at the LHC. Measuring production of hadrons with large $Q^2$ transfer in these collisions provides the possibility to explore one of the most spectacular effects — the in-medium parton energy loss. [...]

Heavy-flavour production measurements in heavy-ion collisions with ALICE at the LHC / Festanti, A (CERN) /ALICE Collaboration
The measurement of heavy-flavour production in ultra-relativistic heavy-ion collisions provides insights into the properties of the Quark-Gluon Plasma (QGP), the state of strongly-interacting matter characterised by high temperature and energy density where quarks and gluons are deconfined. ALICE results on heavy-flavour production in p–Pb and Pb–Pb collisions are presented..

The upgrade of the ALICE Inner Tracking System at the CERN LHC / Ravasengaon, I (INFN, Turin ; Turin Polytechnic) /ALICE Collaboration
In 2021, for the third run of the CERN Large Hadron Collider (LHC), Pb–Pb collisions will be performed at a centre-of-mass energy per nucleon of $\sqrt{s_{NN}}$ = 5.5 TeV, with an integrated luminosity of 6 × 10$^{27}$ cm$^{-2}$ s$^{-1}$ and at an unprecedented interaction rate of 50 kHz. To fulfil the requirements of its physics program for Run 3 the ALICE experiment at LHC is preparing a major upgrade during the Long Shutdown 2 of LHC in 2019-2020. [...]

Performance Evaluation of the Forward Calorimeter Prototype for ALICE / Minato, Yoko (Nara Women's U.) /ALICE Collaboration
The Forward Calorimeter (FoCal) is a new detector as an upgrade project of the ALICE experiment at the Large Hadron Collider (LHC). The primary goal is to measure direct photon and neutral pion production at forward rapidity (3.2 < $\eta$ < 5.3). [...]

Open Heavy-Flavour Measurements in Small Systems with ALICE at the LHC / Dhankher, P (Indian Inst. Tech., Mumbai) /ALICE Collaboration
Heavy quarks (charm and beauty) are produced at the initial stages of hadronic collisions in hard scattering processes. In pp collisions, their production provides a test bed for perturbative QCD calculations and a crucial baseline for p–Pb and Pb–Pb collisions. [...]
