Measurement of correlations among net-charge, net-proton, and net-kaon multiplicity distributions in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV / Acharya, Shreyasi (INFN, Bari) ; Agarwal, Apar (Calcutta, VECC) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al.
Correlations among conserved quantum numbers, such as the net-electric charge, the net-baryon, and the net-strangeness in heavy-ion collisions, are crucial for exploring the QCD phase diagram. In this letter, these correlations are investigated using net-proton number (as a proxy for the net-baryon), net-kaon number (for the net-strangeness), and net-charged particle number in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV with the ALICE detector.

Evidence for J/$\psi$ suppression in incoherent photonuclear production / Acharya, Shreyasi (INFN, Bari) ; Agarwal, Apar (Calcutta, VECC) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al.
According to quantum chromodynamics, at sufficiently high energy, the structure of hadrons reveals a dynamic equilibrium between gluon splitting and gluon recombination—a phenomenon known as saturation. The process of diffractive photonuclear production of a J/$\psi$ vector meson provides a direct insight into the gluon composition of hadrons. [...]

ALICE Fast Interaction Trigger Upgrade / Roslon, Krystian (Warsaw U. of Tech.)
This proceeding provides an expanded overview of the Fast Interaction Trigger (FIT) system performance, focusing on new developments such as the prospective integration of the ALICE Low-Level Front-End Device (ALFRED) into the Detector Control System (DCS) and an upgraded Front-End Electronics (FEE) approach to enhance dynamic range and operational reliability.

Investigating the p-$\pi^{\pm}$ and p-p-$\pi^{\pm}$ dynamics with femtoscopy in pp collisions at $\sqrt{s} = 13$ TeV / Acharya, Shreyasi (Clermont-Ferrand U.) ; Agarwal, Apar (Calcutta, VECC) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al. /ALICE
The interaction between pions and nucleons plays a crucial role in hadron physics. It represents a fundamental building block of the low-energy QCD dynamics and is subject to several resonance excitations [...]

Measurement of $\omega$ meson production in pp and p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV / Acharya, Shreyasi (INFN, Bari) ; Agarwal, Apar (Calcutta, VECC) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al.
We present the measurement of the $p_{\rm T}$-differential production cross section of $\omega$ mesons in pp and p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV at midrapidity by ALICE. In addition, the first measurement of the nuclear modification factor $R_{\text{pPb}}$ for $\omega$ mesons at LHC energies is presented, complementing the existing measurements of lighter neutral mesons such as the $\pi^0$ and $\eta$.

Observation of the $\Omega$(2012) baryon at the LHC / Acharya, Shreyasi (INFN, Bari) ; Agarwal, Apar (Calcutta, VECC) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al.
A signal consistent with the $\Omega$(2012) baryon has been observed with a significance of $15\sigma$ in pp collisions at $\sqrt{s} = 13$ TeV at the LHC. In this paper, the analysis technique is described and measurements of the mass and width of the $\Omega$(2012) are reported, along with the first measurement of its transverse-momentum spectrum and yield.
