Performance highlights from ALICE / Schlepper, Felix (CERN ; U. Heidelberg (main)) /ALICE Collaboration
The ALICE experiment at the CERN LHC has undergone a major upgrade program for Run 3, enabling high-precision studies of the quark-gluon plasma and rare probes in high-multiplicity environments. Key detector improvements, including the new Inner Tracking System (ITS2) with 12.8 billion pixels and a first layer at 22 mm from the nominal interaction point, and a GEM-based Time Projection Chamber, facilitate data taking at a Pb-Pb interaction rate of 50 kHz at $\sqrt{s_{\mathrm{NN}}} = 5.36$ TeV and, in pp, selective rates up to 1 MHz at $\sqrt{s}=13.6$ TeV.The O$^2$ computing framework enables online/offline integration and selective data storage through an offline trigger program, called skimming, compressing datasets to 4.5% of their original size.In 2022-2024, ALICE collected over 4.7 trillion pp events, 72.1 pb${}^{-1}$, and more than 80 PB of Pb-Pb data, 3 nb$^{-1}$, with more than 96% availability.

Study of exotic resonances in pp collisions with ALICE at LHC / Sawan (NISER, Jatni) /ALICE Collaboration
Quantum Chromodynamics predicts the existence of several exotic hadrons in the mass range of 1–2 GeV/c2 whose internal structure is unknown. The ALICE detector, with its excellent particle identification capabilities, has leveraged data from LHC Runs 2 and 3 to study these exotic resonances in detail. [...]

MOnolithic Stitched sensor with Timing (MOST): design overview and measurements highlights / ALICE Collaboration
The MOST (Monolithic Stitched Sensor with Timing) is a 26 cm long wafer-scale pixel sensor prototype that bridges generic R&D; for future High Energy Physics (HEP) detectors with the developments aimed for the ALICE Inner Tracking System (ITS3).Its main purpose is to investigate the yield of high-density pixel architectures, assess the timing capabilities of asynchronous readout, investigate an alternative sensor biasing scheme, evaluate yield enhancing power segmentation and verify a robust bias distribution method resilient to fluctuations of supply voltages.This contribution presents both the design overview of the MOST chip and key measurements that validate its functionality and performance..

Designing the ALICE 3 bRICH detector: Simulation studies and beam test results / Nicassio, N (INFN, Bari ; Bari Polytechnic ; CERN) ; Congedo, L (INFN, Bari) ; De Robertis, G (INFN, Bari) ; Di Bari, D (INFN, Bari ; Bari Polytechnic) ; Di Mauro, A (CERN) ; Durini Romero, D (INAOE, Puebla) ; Giliberti, M (INFN, Bari) ; Kiss, T (Wigner RCP, Budapest) ; Licciulli, F (INFN, Bari) ; Liguori, A (INFN, Bari ; Bari Polytechnic) et al.
The ALICE Collaboration is proposing a completely new apparatus, ALICE 3, for the LHC Run 5. The design target of the ALICE 3 charged particle identification (PID) system is to ensure a better than 3σe/π, π/K and K/p separation for momenta up to 2 GeV/c, 10 GeV/c and 16 GeV/c, respectively. [...]

Testing perturbative QCD calculations with charm-tagged jets and correlations of charm hadrons with charged particles / Cattaruzzi, Samuele (INFN, Turin) /ALICE Collaboration
Measurements of the properties of jets initiated by a charm quark represent a valuable tool to investigate the properties of quantum chromodynamics (QCD) processes such as the evolution of the heavy-flavour-quark parton shower and hadronisation. Casmir colour effects that are different for quarks and gluons and mass effects driven by the dead cone of heavy quarks, impact the properties of the resultant showers and can be accessed by the study of heavy-flavour tagged jets.

Investigating quarkonium production in proton-proton collisions with ALICE / Barreau, Emilie (SUBATECH, Nantes) /ALICE Collaboration
Quarkonium production in high-energy proton-proton (pp) collisions provides a unique probe of both perturbative and non-perturbative aspects of quantum chromodynamics (QCD). Charmonium states, such as the J/$\psi$ and $\psi$(2S), are produced through a two-stage process involving hard parton-parton scatterings followed by non-perturbative hadronization. [...]

The forward calorimeter of the ALICE experiment at CERN LHC / Simeonov, Radoslav (Sofia U. (main)) /ALICE Collaboration
A new forward calorimeter (FoCal), covering the pseudorapidity range 3.4 ≤ η ≤ 5.8, is proposed in order to extend the physics reach of ALICE during the LHC Run 4. The FoCal comprises a high-granularity electromagnetic calorimeter with silicon pixel and pad readout as well as a hadronic calorimeter. [...]
