This paper presents the first measurement of the two-point energy–energy correlator (EEC) inside charged-particle jets in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV with the ALICE experiment. The two-point EEC, an infrared- and collinear-safe measure of angular energy flow within jets, is used to probe both perturbative and non‑perturbative stages of the jet evolution. [...]

Constraining QCD with precise mass measurements of multi-strange baryons
/ ALICE Collaboration, CERN
The $\Omega^-$ baryon, composed of three strange quarks (sss), was predicted using the quark model and discovered in 1964; it played a pivotal role in establishing quarks as fundamental constituents of matter. Despite its importance, experimental knowledge about its mass remains limited, with the current world average relying on measurements performed more than four decades ago and lacking robust estimates of systematic uncertainties. [...]

/ALICE
The measurement of hyperon ($\Lambda$ and $\overline{\Lambda}$) polarization along the beam axis in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.36$ TeV using the ALICE detector is presented. The polarization, arising from vorticity components induced by anisotropic flow, is studied relative to the second- and third-order event planes. [...]

Probing jet evolution with charged energy correlators in small systems

Sci.) et al.
The ALICE Collaboration presents measurements of charged energy$-$energy correlators (charged EECs) within charged-particle jets at $\sqrt{s_{\rm NN}}=5.02$ TeV in proton$-$proton and proton$-$lead collisions at the LHC. Charged EECs are a class of jet substructure observables that trace the flow of energy and electric charge within a jet, and provide a tool for disentangling the energy scales involved in the jet fragmentation process through the angular separation and charges of particle pairs.

Evidence for parton energy loss in oxygen$-$oxygen collisions at $\sqrt{s_{\rm NN}}$ = 5.36TeV
/ ALICE Collaboration, CERN
Ultra-relativistic heavy-ion collisions create a hot and dense medium of deconfined quarks and gluons, the quark$-$gluon plasma (QGP), in which parton energy loss ("jet quenching") is a key probe of hot medium properties. While parton energy loss has been firmly established in large systems such as Pb$-$Pb and Au$-$Au collisions, no unambiguous direct evidence exists in smaller systems such as high-multiplicity p$-$Pb and pp collisions. [...]

Exclusive dimuon production and coherent charmonium photoproduction at forward rapidity in ultra-peripheral Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.36$ TeV

/ALICE
This Paper presents rapidity-differential measurements of coherent J/$\psi$ and $\psi({\rm 2S})$ photoproduction, as well as rapidity- and mass-differential measurements of exclusive dimuon production, in the forward rapidity region $-4 < y < -2.5$ in ultra-peripheral Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.36$ TeV using data recorded by the ALICE detector at the LHC in 2023, corresponding to an integrated luminosity of $\mathcal{L} = 1170 \pm 50~\mu{\rm b}^{-1}$. The J/$\psi$ and $\psi({\rm 2S})$ results reveal the significant role of nuclear shadowing effects. [...]

Measurement of isolated-prompt photon-hadron correlations in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV

The ALICE Collaboration has measured the azimuthal correlation between trigger isolated-prompt photons and associated charged hadrons in Pb-Pb collisions at the CERN LHC, at a centre-of-mass energy per nucleon pair of $\sqrt{s_{\rm NN}} = 5.02$ TeV. The trigger isolated-prompt photons are measured in the transverse-momentum range $18 < p_{\rm T}^\gamma < 40$ GeV/$c$ and pseudorapidity range $|\eta^\gamma| < 0.67$. [...]
