Measurement of beauty production via non-prompt charm hadrons in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV / ALICE Collaboration, CERN /ALICE
The production cross sections of D$^0$, D$^+$, and $\Lambda^{+}_{\rm c}$ hadrons originating from beauty-hadron decays (i.e. non-prompt) were measured for the first time at midrapidity in proton–lead (p-Pb) collisions at the center-of-mass energy per nucleon pair of $\sqrt{s_{\rm NN}} = 5.02$ TeV.

Rapidity dependence of antideuteron coalescence in pp collisions at $\sqrt{s}$ = 13 TeV with ALICE / ALICE Collaboration, CERN /ALICE
The production yields of antideuterons and antiprotons are measured in pp collisions at a center-of-mass energy of $\sqrt{s}$ = 13 TeV, as a function of transverse momentum ($p_{\rm T}$) and rapidity ($y$), for the first time up to $|y|=$ 0.7. The measured spectra are used to study the $p_{\rm T}$ and rapidity dependence of the coalescence parameter $B_2$, which quantifies the coalescence probability of antideuterons. [...]

Prospects of angular correlation studies of identified hadrons in the LHC Run 3 with the ALICE experiment / Chochulska, Zuzanna (Warsaw U. of Tech.)
The study of angular correlations of identified hadrons makes it possible to understand the impact of different processes that contribute to the hadronization mechanism in heavy-ion collisions and small collision systems. [...]

Photoproduction of J/$\psi$ and dileptons in Pb-Pb collisions with nuclear overlap / Bizé, Nicolas (SUBATECH, Nantes)
Photon-photon reactions and the production of J/$\psi$ meson through photonuclear reactions have been extensively studied in ultra-peripheral heavy-ion collisions, in which the impact parameter is larger than twice the nuclear radius. [...]

Measurement of the inclusive isolated-photon production cross section in pp collisions at $\sqrt{s}$ = 13 TeV / Acharya, Shreyasi (Clermont-Ferrand U.) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; 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) et al.
The production cross section of inclusive isolated photons has been measured by the ALICE experiment at the CERN LHC in pp collisions at centre-of-momentum energy of $\sqrt{s}=13$ TeV collected during the LHC Run 2 data-taking period. The measurement is performed by combining the measurements of the electromagnetic calorimeter EMCal and the central tracking detectors ITS and TPC, covering a pseudorapidity range of $|\eta^{\gamma}|<0.67$ and a transverse momentum range of $7<p_{\rm T}^{\gamma}<200$ GeV/$c$.

Probing strangeness hadronization with event-by-event production of multistrange hadrons / Acharya, Shreyasi (Clermont-Ferrand U.) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; 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) et al.
This Letter presents the first measurement of event-by-event fluctuations of the net number (difference between the particle and antiparticle multiplicities) of multistrange hadrons $\Xi^-$ and $\overline{\Xi}^+$ and its correlation with the net-kaon number using the data collected by the ALICE Collaboration in pp, p-Pb, and Pb-Pb collisions at a center-of-mass energy per nucleon pair $\sqrt{s_{\mathrm{NN}}}=5.02\ \mathrm{TeV}$. The statistical hadronization model with a correlation over three units of rapidity between hadrons having the same and opposite strangeness content successfully describes the results. [...]
