In this letter, the first measurement of the femtoscopic correlation of protons and $\Sigma^+$ hyperons is presented and used to study the p$-\Sigma^+$ interaction. The measurement is performed with the ALICE detector in high-multiplicity triggered pp collisions at $\sqrt{s} = 13$ TeV. [...]

Meson-baryon systems with strangeness content provide a unique laboratory for investigating the strong interaction and testing theoretical models of hadron structure and dynamics. In this work, the measured correlation functions for oppositely charged $\Xi - \mathrm{K}$ and $\Xi -\pi$ pairs obtained in high-multiplicity pp collisions at $\sqrt{s} = 13$ TeV at the LHC are presented.

Evidence of nuclear geometry-driven anisotropic flow in OO and Ne$-$Ne collisions at $\sqrt{s_{\rm NN}}=5.36$ TeV
/ Abualrob, Ibrahim Jaser (Houston U.) ; Acharya, Shreyasi (INFN, Bari) ; 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.) ; Akbar, Zulkaida (Jakarta LIPI, Indonesian Inst. Sci.) ; Akindinov, Alexander (Unlisted) et al.
A central question in strong-interaction physics, governed by quantum chromodynamics (QCD), is whether femto-scale droplets of quark--gluon plasma (QGP) form in small collision systems involving projectiles significantly smaller than heavy ions. Collisions of light ions such as $^{16}$O and $^{20}$Ne offer a unique opportunity to probe the emergence of collective behavior in QCD matter. [...]

/ALICE
Direct measurements of the $\rho^0$p interaction have remained so far elusive, with most insights derived indirectly from photoproduction or low-energy partial wave analyses. This letter presents the first direct observation of the $\rho^0$p interaction, obtained through two-particle correlations measured in high-multiplicity, ultrarelativistic proton-proton collisions at $\sqrt{s} = 13$ TeV by the ALICE Collaboration at the LHC.

Sci.) et al.
The first measurement at midrapidity ($|y|< 0.5$) of the production yield of the strange-charm baryons $\Xi_{\rm c}^+$ and $\Xi_{\rm c}^0$ as a function of charged-particle multiplicity in proton$-$proton collisions at $\sqrt{s}=13$ TeV with the ALICE experiment at the LHC is reported. The $\Xi_{\rm c}^+$ baryon is reconstructed via the $\Xi_{\rm c}^+ \rightarrow \Xi^- \pi^+ \pi^+$ decay channel in the range $ 4 < p_{\rm T} <12$ GeV/$c$, while the $\Xi_{\rm c}^0$ baryon is reconstructed via both the $\Xi_{\rm c}^0 \longrightarrow \Xi^- \pi^+$ and $\Xi_{\rm c}^0 \rightarrow {\rm e}^+ \nu_{\rm e}$ decay channels in the range $2 < p_{\rm T} <12$ GeV/$c$.
