 System and event activity dependent inclusive jet production with ALICE / Hou, Yongzhen (Hua-Zhong Normal U., LQLP) /ALICE Collaboration Jets are produced by processes involving high momentum transfer of initial partons at high energies. Comparing jet production in pp and nucleus-nucleus collisions will allow us to study the jet-quenching effect caused by the hot and dense QCD medium produced in nucleus-nucleus collisions when energetic partons traverse the medium.

 Upgrade of ALICE forward detectors / Slupecki, Maciej (Jyvaskyla U.) /ALICE Collaboration ALICE will upgrade its subsystems in 2019-2020 to fully benefit from the increased collision rate and luminosity of the LHC at CERN. Two new forward detectors will be installed at the core of ALICE: the Fast Interaction Trigger (FIT) and the Muon Forward Tracker (MFT).

 Direct-photon elliptic flow in Pb-Pb collisions at $\sqrt{s_\rm{NN}}=2.76$ TeV / Sas, Mike (Utrecht U. (main) ; Nikhef, Amsterdam) /ALICE Collaboration The elliptic flow of inclusive and direct photons was measured by ALICE for central and semi-central Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$=2.76 TeV. The photons were reconstructed using the electromagnetic calorimeter PHOS and the central tracking system.

 Probing charm hadronisation with ALICE at the LHC / Bedda, Cristina (Utrecht U. (main)) /ALICE Collaboration Charm-quark hadronisation can be investigated by measuring the relative abundance of various particle species, in particular non-strange D mesons ($\rm{D^0}$, $\rm{D^+}$, $\rm{D^{*+}}$), $\rm{D_s^+}$ mesons, and charm baryons ($\rm{\Lambda_{c}^+}$, $\rm{\Xi_c^0}$). The high precision tracking, excellent vertexing capabilities and particle identification granted by the ALICE apparatus allows hadrons containing charm quarks to be measured over a wide momentum range in pp and pA collisions.

 Anisotropic flow of identified particles in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV with ALICE / Zhu, Ya (Hua-Zhong Normal U.) /ALICE Collaboration Anisotropic flow plays a critical role in understanding the properties of the quark-gluon plasma. The elliptic and triangular flow at mid-rapidity of identified particles, including $\pi^{\pm}$, $\rm K^{\pm}$, $\rm p +\bar{p}$, $\phi$, $\rm K^{0}_{S}$, $\Lambda + \bar{\Lambda}$, $\Xi^{-}+\bar{\Xi}^{+}$ and $\Omega^{-}+\bar{\Omega}^{+}$ were measured by ALICE for Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV.

 Transverse momentum distributions of charged particles in pp and nuclear collisions with ALICE at the LHC / Perez Lezama, Edgar (Darmstadt, GSI ; Goethe U., Frankfurt (main)) /ALICE Collaboration The charged-particle transverse momentum spectrum in pp collisions is an important observable for testing perturbative QCD calculations and serves as a reference for heavy-ion collisions to study the properties of deconfined matter created in nucleus-nucleus (AA) collisions. The study of inclusive charged particle spectra gives information on parton energy loss in the medium created in AA collisions, leading to a suppression of hadron production at high transverse momentum ($p_{\rm T}$).

 Spin alignment measurements of K$^{∗0}$ vector mesons with ALICE at the LHC / Kundu, Sourav (NISER, Jatni) /ALICE Collaboration We present the recent spin alignment measurements of K$^{*0}$ vector mesons at mid-rapidity ($|y|$$<$0.5) in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 2.76 TeV and 5.02 TeV and in pp collisions at $\sqrt{s}$ = 13 TeV, performed with the ALICE detector at the LHC. Spin alignment measurements of K$^{*0}$ vector mesons are performed with respect to the production plane and second order event plane.

 Investigating jet modification in heavy-ion collisions at $\sqrt s_{NN}$ = 5.02 and 2.76 TeV with ALICE / Yokoyama, Hiroki (Tsukuba U. (main)) /ALICE Collaboration The LHC heavy-ion physics program aims at investigating the fundamental properties of nuclear matter under extreme conditions of energy density and temperature, where a transition to a Quark-Gluon Plasma (QGP) is expected. Jets, defined as sprays of hadrons resulting from the fragmentation of high-energy partons, are among the most powerful probes of QGP transport properties.

 Soft QCD measurements with ALICE / Kim, Beomkyu (Inha U.) /ALICE Collaboration Particle production at LHC energies involves perturbative (hard) and non-perturbative (soft) QCD regimes. At low transverse momentum it is generally described by phenomenological models.

 Study of production of electrons from beauty-hadron decays in pp collisions at $\sqrt{s}$ = 13 TeV and Pb-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV with ALICE / Park, Jonghan (Inha U.) ; Kwon, Jiyeon (Inha U.) /ALICE Collaboration Heavy quarks, charm and beauty, are expected to be effective probes for the hot and dense medium (QGP) produced in high-energy heavy-ion collisions. They are produced in the early stage of the collision, almost exclusively in hard partonic scattering, and therefore they experience the full evolution of the QGP allowing to study the in-medium partonic energy-loss.
