Shedding light on light-flavour-particle production in small systems at the LHC with ALICE / Ercolessi, Francesca (INFN, Bologna) /ALICE Collaboration
The measurement of light-flavour-particle production in small collision systems at the LHC has shown features that resemble phenomena seen in heavy-ion collisions. The historical signatures of the quark–gluon plasma (QGP) formation, such as collective flow and the enhanced production of strange hadrons, were also observed in high-multiplicity proton–proton (pp) and proton–lead (p–Pb) collisions.

Experimental overview on open-heavy flavours / Grosa, Fabrizio (CERN)
Heavy flavours, i.e. charm and beauty quarks, are recognised as excellent probes of the colour-deconfined medium created in ultrarelativistic heavy–ion collisions, the quark–gluon plasma (QGP). [...]

Probing parton propagation in heavy-ion collisions with ALICE heavy-flavour measurements / Singh, Ravindra (Darmstadt, GSI) /ALICE Collaboration
Heavy quarks (charm and beauty) are valuable probes for investigating the properties of the quark–gluon plasma (QGP) formed in ultra-relativistic heavy-ion collisions, as they are mainly produced through hard-scattering processes prior to the formation of the QGP, and their number is conserved during the subsequent QGP evolution. Measurements of the nuclear modification factor RAA of charm and beauty hadrons allow us to characterise the in-medium energy loss of heavy quarks while traversing the QGP. [...]

Vector meson polarisation in heavy-ion collisions at the LHC / Micheletti, Luca (CERN) /ALICE Collaboration
Heavy quarks, i.e. charm and beauty, are produced in the initial stage of heavy-ion collisions, on a time scale shorter than the medium formation time, and are sensitive to the large initial magnetic field produced perpendicular to the reaction plane, defined by the impact parameter direction and beam direction, in non-central heavy-ion collisions.

Exploring the internal structure of exotic resonances with ALICE / Padhan, Sonali (Indian Inst. Tech., Mumbai) /ALICE Collaboration
The investigation of the quark content of hadrons has been a major goal of nonperturbative strong interaction physics. In the last decade, several resonances in the mass range 1000-2000 MeV/c2 have emerged that cannot be explained by the quark model. [...]

Jet energy redistribution and broadening using hadron+jet measurements in pp and Pb–Pb collisions with ALICE / Norman, Jaime (Liverpool U.) /ALICE Collaboration
In this contribution we present measurements of the semi-inclusive distributions of charged jets recoiling from a trigger hadron (hadron+jet) in pp and Pb–Pb collisions, which provide unique probes of medium-induced modification of jet production. We observe that the jet yield at low pT and at large azimuthal angle between the trigger hadron and jet is significantly enhanced in Pb–Pb collisions with respect to pp collisions, which we interpret through comparisons to model calculations..

Pinning down the origin of collective flow in small systems with ALICE / Zhao, Mingrui (Beijing, Inst. Atomic Energy ; Bohr Inst.) /ALICE Collaboration
In this proceeding, the new preliminary results of anisotropic flow in pp, p–Pb, and Pb–Pb collisions measured with ALICE are presented. The highlights include the flow of charged particles, correlations and fluctuations of flow vectors, and correlations between the mean transverse momentum and flow coefficients, ρ(vn2,[pT]). [...]

Exploring the hadron gas phase of relativistic heavy-ion collisions at the LHC / Agrawal, Neelima (Bologna U. ; INFN, Bologna) /ALICE Collaboration
The lifetimes of hadronic resonances are comparable to the one of the hadron gas phase created in the late stages of high-energy nuclear collisions. Therefore, a significant fraction of resonances decay inside a high-density medium and their decay daughters rescatter with nearby hadrons destroying their initial kinematic correlations. [...]

Constraining the low-x structure of nuclei with LHCb / Boettcher, Thomas (Cincinnati U.) /LHCb Collaboration
The LHCb detector’s forward geometry provides unprecedented access to the very low regions of Bjorken x inside the nucleon. With full particle ID and a fast DAQ, LHCb is able to fully reconstruct plentiful charged particles and neutral mesons, as well as relatively rare probes such as heavy quarks, providing a unique set of constraints on nucleon structure functions.

Recent charmonium measurements in Pb–Pb collisions with ALICE / Bai, Xiaozhi (Hefei, CUST) /ALICE Collaboration
Charmonia have long been recognized as a valuable probe of the nuclear matter in extreme conditions, the strongly interacting medium created in heavy-ion collisions known as quark-gluon plasma (QGP). At LHC energies, the (re-)generation process due to the abundantly produced charm quarks, was found to considerably affect measured charmonium observables. [...]
