Charm production and hadronisation in pp and p--Pb collisions at $\sqrt{s_{\rm NN}} = $ 5.02 TeV at the LHC with ALICE / Cheng, Tiantian (Hua-Zhong Normal U. ; Darmstadt, GSI)
Production measurements of charm hadrons, particularly the yield ratios of different hadron species as a function of the transverse momentum, are important to study the charm hadronisation mechanism. [...]

Recent ALICE results relevant for PDFs at low and high-$x$, saturation / Khatun, Anisa
We present recent results from the ALICE Collaboration on the study of coherent and incoherent J/$\psi$ photoproduction in ultra-peripheral Pb-Pb collisions, including results from exclusive and dissociate J/$\psi$ mesons in ultra-peripheral p-Pb interactions. [...]

First measurement of symmetric cumulants of hexagonal flow harmonics in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV / Acharya, Shreyasi (INFN, Bari) ; Agarwal, Apar (Calcutta, VECC) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al.
Correlations between event-by-event fluctuations of anisotropic flow harmonics are measured in Pb-Pb collisions at a center-of-mass energy per nucleon pair of 5.02~TeV, as recorded by the ALICE detector at the LHC. This study presents correlations up to the hexagonal flow harmonic, $v_6$, which was measured for the first time. [...]

Recent results on heavy flavours and quarkonia from ALICE / Fionda, Fiorella (Cagliari U. ; INFN, Cagliari)
Heavy-flavour hadrons, containing at least one charm or beauty quark, are excellent probes of the deconfined medium created in ultra-relativistic heavy-ion collisions, known as quark-gluon plasma. [...]

Light neutral-meson production in pp collisions at $\mathbf{\sqrt{s}}$ = 13 TeV / Acharya, Shreyasi (Clermont-Ferrand U.) ; Agarwal, Apar (Calcutta, VECC) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al.
The momentum-differential invariant cross~sections of ${\pi^{0}}$ and $\eta$ mesons are reported for pp collisions at $\sqrt{s} = 13$ TeV at midrapidity ($|y| < 0.8$). The measurement is performed in a broad transverse-momentum range of $0.2 < p_{\rm T} < 200$ GeV/$c$ and $0.4 < p_{\rm T} < 60$ GeV/$c$ for the ${\pi^{0}}$ and $\eta$, respectively, extending the $p_{\rm T}$ coverage of previous measurements.

Study of baryon-strangeness and charge-strangeness correlations in Pb$-$Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV with ALICE / Saha, Swati (Bhubaneswar, NISER ; HBNI, Mumbai)
In the quest to unravel the mysteries of the strong force and the underlying properties of the quark-gluon plasma, the ALICE collaboration at CERN has carried out a comprehensive study focusing on the correlations between net-conserved quantities such as net-baryon, net-charge and net-strangeness.
