The first measurement of the elliptic flow coefficient of (anti)${}^3_{\Lambda}$H and the study of the $v_2$ of $^3\overline{\mathrm{He}}$ measured in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} = 5.36$ TeV with the ALICE detector are presented. Based on the large data sample of approximately five billion events collected in 2023 during the LHC Run 3 data taking, these measurements provide important insights into the production mechanism of (anti)(hyper)nuclei, as well as into the phase-space distributions of nucleons and hyperons produced in heavy-ion collisions [...]

This article reports the measurement of the transverse-momentum ($p_\mathrm{T}$) differential production cross section of $\mathrm{B^0}$ mesons in proton$-$proton collisions at a centre-of-mass energy of $\sqrt{s}=13.6~\mathrm{TeV}$ with the ALICE detector at the CERN LHC. For the first time, the $\mathrm{B^0}$ production cross section is measured at midrapidity ($|y|<0.5$) down to $p_\mathrm{T}=1~\mathrm{GeV}/c$ at LHC energies. [...]

/ Ali Hassan Abdallah, Dana (Wayne State U.) ; Abualrob, Ibrahim Jaser (Houston U.) ; Acharya, Shreyasi (INFN, Bari) ; Agarwal, Kshitij (Trieste U. ; INFN, Trieste) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahuja, Ishaan (Kosice U.) et al.
The first measurements of the average transverse-momentum fraction ($\langle z \rangle$) as a function of transverse momentum ($p_{\rm T}$) for strange baryons ($\Lambda$ and $\bar{\Lambda}$) and strange mesons (K$^0_{\rm S}$), produced in mini-jets defined through angular correlations in pp collisions at $\sqrt{s}=13$ TeV, are reported by the ALICE Collaboration at the LHC. The observable is obtained using a novel method, where the angular correlation between the strange hadrons and inclusive charged hadrons is weighted by the $p_{\rm T}$ of correlated particles at small angular distance.

The ALICE collaboration reports the azimuthal-anisotropy coefficient $v_2$ of prompt D$^0$, D$^+$, D$_{\rm s}^+$ mesons and the first measurement of $v_2$ of prompt $\Lambda_{\rm c}^+$ baryons in semicentral Pb$-$Pb collisions at a center-of-mass energy per nucleon pair of $\sqrt{s_{\rm NN}} = 5.36$ TeV. The D mesons and $\Lambda_{\rm c}^+$ baryons are reconstructed in their hadronic decays at midrapidity ($|y| < 0.8$) in the transverse-momentum interval $0.5 < p_{\rm T} < 24$ GeV/$c$ [...]

Measurements of the event-by-event correlation between elliptic flow ($v_2$) and the mean transverse momentum ($[p_{\rm T}]$) using the modified Pearson correlation coefficient $\rho(v_2^2,[p_{\rm T}])$ are reported in pp collisions at $\sqrt{s} = 13$ TeV, and in p$-$Pb and Pb$-$Pb collisions at a center-of-mass energy per nucleon pair $\sqrt{s_{_\mathrm{NN}}} = 5.02$ TeV. This analysis is based on the full LHC Run 2 dataset recorded by ALICE and is performed for the first time in small collision systems with the ALICE detector. [...]

We make predictions for the expected multiplicities of exotic charmed hadrons and charmed nuclei in Au+Au collisions at SIS100 and LHC beam energies, using input on light hadron and charm production from the UrQMD transport model, and applying the Thermal-FIST model. [...]
