 Measurements of inclusive J/$\psi$ production at midrapidity and forward rapidity in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV / ALICE Collaboration, CERN The measurements of the inclusive J/$\psi$ yield at midrapidity ($|y| < 0.9$ and forward rapidity ($2.5 < y < 4$) in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV with the ALICE detector at the LHC are reported. The inclusive J/$\psi$ production yields and nuclear modification factors, $R_{\rm AA}$, are measured as a function of the collision centrality, J/$\psi$ transverse momentum ($p_{\rm T}$), and rapidity.

 Measurement of inclusive J/$\psi$ pair production cross section in pp collisions at $\sqrt{s} = 13$ TeV / ALICE Collaboration, CERN /ALICE The production cross section of inclusive J/$\psi$ pairs in pp collisions at a centre-of-mass energy $\sqrt{s} = 13$ TeV is measured with ALICE. The measurement is performed for J/$\psi$ in the rapidity interval $2.5 < y < 4.0$ and for transverse momentum $p_{\rm T} > 0$. [...] CERN-EP-2023-053.- Geneva : CERN, 2023 Draft (restricted): PDF;

 Study of the p$-$p$-$K$^+$ and p$-$p$-$K$^-$ dynamics using the femtoscopy technique / ALICE Collaboration, CERN /ALICE The interactions of kaons (K) and antikaons ($\mathrm{\overline{K}}$) with few nucleons (N) were studied so far using kaonic atom data and measurements of kaon production and interaction yields in nuclei. Some details of the three-body KNN and $\mathrm{\overline{K}}$NN dynamics are still not well understood, mainly due to the overlap with multi-nucleon interactions in nuclei.

 Higher-order correlations between different moments of two flow amplitudes in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV / ALICE Collaboration, CERN /ALICE The correlations between different moments of two flow amplitudes, extracted with the recently developed asymmetric cumulants, are measured in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV recorded by the ALICE detector at the LHC. The magnitudes of the measured observables show a dependence on the different moments as well as on the collision centrality, indicating the presence of non-linear response in all even moments up to the eighth.

 Measurement of the angle between jet axes in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV$/ ALICE Collaboration, CERN This letter presents the first measurement of the angle between different jet axes (denoted as${\Delta}R$) in Pb$-$Pb collisions. The measurement is carried out in the 0$-$10% most-central events at$\sqrt{s_ {\rm NN}} = 5.02$TeV.

Moreover, it influences many aspects of the charged-particle reconstruction performance.

In p$-$Pb collisions, the production cross section and the nuclear modification factor of electrons from heavy-flavour hadron decays are measured in the$p_{\rm T}$range 0.5$< p_{\rm T} <$26 GeV$/c$at$\sqrt{s_{\textrm{NN}}}=8.16~{\rm TeV}$[...] CERN-EP-2023-041.- Geneva : CERN, 2023 Draft (restricted): PDF; 2023-02-27 17:40  Measurement of the radius dependence of charged-particle jet suppression in Pb–Pb collisions at$\sqrt{s_{\rm NN}} = 5.02$TeV The ALICE Collaboration reports a new differential measurement of inclusive jet suppression using pp and Pb–Pb collision data at center-of-mass energy per nucleon–nucleon collision$\sqrt{s_{\rm NN}} = 5.02$TeV.
