Measurements of groomed-jet substructure of charm jets tagged by ${\rm D}^0$ mesons in proton–proton collisions at $\sqrt{s}$ = 13 TeV / ALICE Collaboration, CERN
Understanding the role of parton mass and Casimir colour factors in the quantum chromodynamics parton shower represents an important step in characterising the emission properties of heavy quarks. Recent experimental advances in jet substructure techniques have provided the opportunity to isolate and characterise gluon emissions from heavy quarks. [...]

Charmonium production as a function of charged-particle multiplicity in pp and p--Pb collisions with ALICE at the LHC / Tork, Theraa
Heavy quarkonium production is an excellent tool to test both perturbative and non-perturbative QCD, as perturbative QCD can describe the heavy quark production process, while the formation of the quarkonium bound state involves non-perturbative aspects. [...]

Beauty production in heavy-ion collisions with ALICE at the LHC / Peng, Xinye (Chinese U. of Geoscience, Wuhan ; Hua-Zhong Normal U.)
In this contribution, the final measurements of the centrality dependence of the nuclear modification factor ($R_{\rm AA}$) of non-prompt $\rm D^0$ in Pb--Pb collisions at $\sqrt{s_{\scriptscriptstyle \rm NN}}$ = 5.02 TeV will be presented. [...]

Particle production as a function of underlying-event activity and search for jet-like modifications in pp, p-Pb, and Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV with ALICE / Ortiz, Antonio
The similarity between small- and large-collision systems is explored using the charged-particle multiplicity in the transverse region, $N^{\rm T}_{\rm ch}$, which is sensitive to the underlying event. [...]

${\rm f}_{0}(980)$ production in inelastic pp collisions at $\sqrt{s} = 5.02$ TeV / ALICE Collaboration, CERN /ALICE Collaboration ; ALICE
The measurement of the production of ${\rm f}_{0}(980)$ in inelastic pp collisions at $\sqrt{s} = 5.02$ TeV is presented. This is the first reported measurement of inclusive ${\rm f}_{0}(980)$ production at LHC energies. [...]

Anisotropic flow and flow fluctuations of identified hadrons in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV /ALICE Collaboration
The first measurements of elliptic flow of $\pi^\pm$, ${\rm K}^\pm$, p+$\overline{\rm p}$, ${\rm K_{S}^0}$, $\Lambda$+$\overline{\Lambda}$, $\phi$, $\Xi^-$+$\Xi^+$, and $\Omega^-$+$\Omega^+$ using multiparticle cumulants in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV are presented. Results obtained with two- ($v_2\{2\}$) and four-particle cumulants ($v_2\{4\}$) are shown as a function of transverse momentum, $p_{\rm T}$, for various collision centrality intervals. [...]
