Energy-energy correlators in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV
/ ALICE Collaboration, CERN
/ALICE
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. [...]

Probing jet evolution with charged energy correlators in small systems
/ ALICE Collaboration, CERN
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. [...]

/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
/ 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 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 $|\eta^\gamma| < 0.67$. [...]

$\mathbf{{\rm K}^{0}_{\rm S}-{\rm K}^{0}_{\rm S}}$ femtoscopy in Pb$-$Pb collisions at $\mathbf{\sqrt{\mathbf{\textit{s}}_{\textbf{NN}}} = 5.02~\textbf{TeV}}$ at the LHC

Results from a one-dimensional femtoscopic analysis of ${\rm K}^{0}_{\rm{S}}-{\rm K}^{0}_{\rm{S}}$ correlations in Pb$-$Pb collisions at the center-of-mass energy $\sqrt{s_{\mathrm{NN}}}~=~5.02$ TeV using data collected by the ALICE experiment at the LHC are presented. The source radius $R$ and correlation strength $\lambda$ are studied as a function of centrality and pair-transverse momentum ($k_{\rm T}$) to provide insight into the space-time structure and composition of the particle-emitting source.

Multiplicity dependence of prompt and non-prompt $\boldsymbol{\mathrm{J}/\psi}$ production at midrapidity in pp collisions at $\mathbf{\sqrt{\textit{s}} = 13}$ TeV
/ 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 yields of prompt and non-prompt ${\rm J}/\psi$ and the fraction of non-prompt ${\rm J}/\psi$ are measured at midrapidity ($|y|<0.9$) via the dielectron decay channel as a function of the midrapidity charged-particle multiplicity ($|\eta|<0.9$) in pp collisions at $\sqrt{s} = 13$ TeV. The ${\rm J}/\psi$ yields and the multiplicity are normalized by their average value in inelastic collisions. [...]

/ALICE
The interaction between nucleons and hyperons -- baryons containing a strange quark -- is key to understanding the properties of dense nuclear matter, such as that expected in the interior of neutron stars. Direct scattering experiments are hindered by the short lifetime of hyperons, prompting the study of hypernuclei -- bound states of nucleons and hyperons -- as an alternative approach [...]

The ALICE collaboration presents the first measurement of the dijet invariant mass spectra of charged-particle jets in pp and p$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV. Charged particles in the mid-pseudorapidity region, $|\eta|<0.9$, are clustered into jets using the anti-$k_{\rm T}$ algorithm with a resolution parameter $R=0.4$. [...]
