 Quarkonium polarization in Pb-Pb collisions at the LHC with ALICE / Michelettion, Luca (INFN, Turin) /ALICE Collaboration Polarization measurements represent an important tool to investigate the production mechanisms of quarkonia, bound states of two heavy quarks (charm or bottom), in proton-proton collisions. Nevertheless, the very small polarization measured at the LHC represents a long-lasting challenge for theoretical models.

 Measurement of $^3\overline {He}$ absorption cross-section with ALICE / Larionov, P (Frascati) ; Königstorfer, S (Munich, Tech. U.) /ALICE Collaboration The measurement of cosmic antinuclei may reveal exotic physics processes such as dark matter annihilation. In this context, $^3\overline {He}$ is one of the most promising probes for these studies, which in particular require precision knowledge of the interaction of these particles with matter.

 Measurement of light (anti)nuclei production with ALICE / Balbino, A (INFN, Turin ; Turin Polytechnic) /ALICE Collaboration At the Large Hadron Collider light (anti)nuclei are produced in proton-proton (pp), proton-lead (p–Pb) and lead-lead (Pb–Pb) collisions. The production mechanism of light (anti)nuclei is an open question in high-energy physics. The measurement of the production spectra and yields allows to improve our understanding of the late stages in the evolution of high-energy collisions.

 Electroweak boson production in heavy-ion collisions with ALICE / Valleon, N (INFN, Pavia ; Pavia U.) /ALICE Collaboration Electroweak boson production in hadronic processes is a clean tool for the investigation of the parton distribution functions (PDFs). This is especially true in heavy-ion collisions at the LHC, where the initial state is largely unconstrained from measurements and important for the interpretation of the system evolution.

 Measurements of charm production in pp collisions with ALICE / Cheng, Tiantian (Lund U. ; Hua-Zhong Normal U. ; Darmstadt, GSI) The production of charm-hadrons at midrapidity in pp collisions at $\sqrt{s}$ = 5.02 and 13 TeV was recently measured by the ALICE Collaboration.

 First measurement of $\rm \Omega_c^0$ production in pp collisions at $\sqrt{s}=13$ TeV with ALICE / Zhu, Jianhui (CCNU, Wuhan, Inst. Part. Phys. ; Darmstadt, GSI) /ALICE Collaboration Recent measurements of charm-baryon production in proton--proton (pp) collisions at midrapidity by the ALICE collaboration showed that baryon-to-meson yield ratios are significantly higher than those measured in $\rm e^+e^-$ collisions. The charm baryon-to-meson and charm baryon-to-baryon yield ratios provide unique information on hadronization mechanisms since the contributions from parton distribution function and parton--parton scattering terms cancel in the ratios.

 New results on the modification of jet structure in Heavy Ion collisions / Santos, Helena (LIP, Lisbon) /ALICE Collaboration ; ATLAS Collaboration ; CMS Collaboration These proceedings report recent studies performed by the ALICE, ATLAS and CMS experiments on jet substructure in $pp$ and Pb+Pb collisions at $\sqrt{sNN}$ = 5.02 TeV. The dependence of the modification of the jet shape on the dijet transverse momentum asymmetry is presented.

 Investigating the hyperon-nucleon strong interaction with a precision measurement of the hypertriton lifetime in ALICE / Mazzaschi, Francesco (INFN, Turin ; Turin U.) /ALICE Collaboration The hypertriton is a bound state of a proton, a neutron and a Λ baryon. Studying its internalstructure is crucial to investigate the hyperon–nucleon strong interaction and offers insights intothe inner core of neutron stars, where Λ production is favoured.
