 Enhanced deuteron coalescence probability in jets. Supplemental Material: a model based on PYTHIA 8 and simple nucleon coalescence} /ALICE collaboration This Note contains a detailed description of a simple nucleon coalescence model, where the phase space distributions of nucleons are generated using PYTHIA 8 with the Monash 2013 tuning. The predictions of this model can be compared to measurements of the transverse-momentum ($p_{\rm T}$) spectra and coalescence parameters $B_2$ of (anti)deuterons in pp collisions at $\sqrt{s} =$13 TeV, in and out of jets [...] ALICE-PUBLIC-2022-019.- Geneva : CERN, 2022 Fulltext: PDF;

 Physics Preliminary Summary: W$^\pm$-boson production in p$-$Pb collisions at $\sqrt{s_{NN}} = 8.16$ TeV and Pb$-$Pb collisions at $\sqrt{s_{NN}} = 5.02$ TeV /ALICE collaboration The production of the W$^\pm$ bosons measured in p$-$Pb collisions at a centre-of-mass energy per nucleon--nucleon collision $\sqrt{s_{\rm NN}} = 8.16$ TeV and Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV with ALICE at the LHC is presented. The W$^\pm$ bosons are measured via their muonic decay channel, with the muon reconstructed in the pseudorapidity region $-4 < \eta^\mu_{\rm lab} < -2.5$ with transverse momentum $p_{\rm T}^\mu > 10$ GeV/$c$.

 Physics Preliminary Summary: Measurement of the production of charm jets tagged with ${\rm D^{0}}$ mesons in pp collisions at $\sqrt{s}$ = 5.02 and 13 TeV /ALICE collaboration The measurement of the production of charm jets, identified by the presence of a ${\rm D^0}$ meson in the jet constituents, is presented in proton–proton collisions at centre-of-mass energies of $\sqrt{s}$ = 5.02 and 13 TeV with the ALICE detector at the CERN LHC. The D0 mesons were reconstructed from their hadronic decay ${\rm D^0} \rightarrow {\rm K^-}\pi^+$ and the respective charge conjugate. [...] ALICE-PUBLIC-2022-017.- Geneva : CERN, 2022 - 26.

 Physics Preliminary Summary: Measurement of inclusive and leading subjet fragmentation in pp and Pb–Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV /ALICE collaboration This Note presents new measurements of the fragmentation properties of jets in both proton–proton (pp) and heavy-ion collisions with the ALICE experiment at the Large Hadron Collider (LHC).

 Physics Preliminary Summary: Measurements of the groomed jet radius and momentum splitting fraction with the soft drop and dynamical grooming algorithms in pp collisions at $\sqrt{s}=5.02$ TeV /ALICE collaboration This Note presents measurements of the groomed jet radius and momentum splitting fraction in pp collisions at $\sqrt{s}=5.02$ TeV with the ALICE detector at the Large Hadron Collider.
