TCAD and charge transport simulations of MAPS in 65 nm for the ALICE ITS3 / Sanna, I (Munich, Tech. U. ; CERN) ; Lemoine, C (CERN ; Strasbourg, IPHC) ; Borghello, G (CERN) ; Snoeys, W (CERN) /ALICE Collaboration
As part of the upgrade to the Inner Tracking System 3 (ITS3) for ALICE and the strategicR&D; programme of the CERN EP department, stitched Monolithic Active Pixel Sensors (MAPS) arebeing developed using a 65 nm CMOS imaging process. Several sensor prototypes were characterizedin laboratory using radioactive sources, particularly the $^{55}$Fe source, which was extensivelyused. [...]

Yield, noise and timing studies of ALICE ITS3 stitched sensor test structures: The MOST / ALICE Collaboration
In the LHC long shutdown 3, the ALICE experiment upgrades the inner layers of its Inner Tracker System with three layers of wafer-scale stitched sensors bent around the beam pipe. Two stitched sensor evaluation structures, the MOnolithic Stitched Sensor (MOSS) and MOnolithic Stitched Sensor with Timing (MOST) allow the study of yield dependence on circuit density, power supply segmentation, stitching demonstration for power and data transmission, performance dependence on reverse bias, charge collection performance, parameter uniformity across the chip, and performance of wafer-scale data transmission.

Charged-particle production in pp collisions at 13.6 TeV and Pb-Pb collisions at 5.36 TeV with ALICE / Tripathy, Tulika (LPC, Clermont-Ferrand)
The first measurements of the charged-particle pseudorapidity density, ${\rm d}N_{\rm{ch}}/{\rm d}η$, in proton-proton (pp) collisions at $\sqrt{s} =$ 13.6 TeV and in lead-lead (Pb-Pb) collisions at $\sqrt{s_{\rm{NN}}} = $ 5.36 TeV are presented. [...]

High Luminosity LHC Optics Feasibility Studies for: ATLAS, ALICE, and LHCb / Patel, Pragati (Cracow, INP) ; Trzebiński, Maciej (Cracow, INP)
Properties of proton trajectories along the High Luminosity LHC beam-line in the vicinity of ATLAS, ALICE, and LHCb interaction points are discussed. Based on this, possible locations of forward proton detectors in the vicinity of these experiments were identified. [...]

MLR1: CMOS MAPS technology validation for ALICE ITS3 / Sturniolo, A (INFN, Catania ; Catania U. ; Catania, CSFNSM) /ALICE Collaboration
The second ALICE Inner Tracking System upgrade project (ITS3), to be completed during LHC Long Shutdown 3 (LS3, 2026-2028), will dramatically reduce the Inner Barrel (IB) detectors’ material budget and thus improve the ITS tracking capabilities (detection efficiency and track resolution). For this purpose, the ITS3 project envisions replacing the current ITS2 IB with 6 flexible, truly cylindrical half-layers, supported only by a carbon foam frame and cooled down by an air system.

ITS3: the next upgrade of the ALICE Inner Tracking System / La Rocca, Paola (Catania U. ; INFN, Catania) /ALICE Collaboration
The ALICE experiment, optimized to study nuclei collisions at the ultra relativistic energies provided by the LHC, is approaching to a new upgrade phase, foreseen in 2026 during the third Long Shutdown of the accelerator. This upgrade includes the replacement of the 3 innermost layers of the Inner Tracking System, the detector closest to the interaction point, which is currently made of 7 layers of Monolithic Active Pixels Sensors (MAPS).

Cosmic $\overline{d}$ and $\overline{He}$: production mechanisms and latest constraints from ALICE at the LHC / Malfattore, G (INFN, Bologna ; Bologna U.) /ALICE Collaboration
The formation mechanism of light (anti)nuclei in high-energy hadronic collisions remains an open question in high-energy physics. Their production mechanism is investigated by comparing experimental data with phenomenological models using statistical hadronization or a coalescence approach.In particular, the coalescence mechanism finds an essential application in cosmic antinuclei studies for indirect dark matter searches with space-based experiments like AMS.

The ALICE ITS3 upgrade project: Latest results on monolithic pixel sensors test structures realized in a 65 nm technology / Savino, U (INFN, Turin ; Turin U.) /ALICE Collaboration
ALICE (A Large Ion Collider Experiment) at CERN investigates the properties of the quark-gluon plasma formed in heavy ion collisions at high energies. A crucial aspect of this research is the precise reconstruction of low momentum particles (< 1 GeV/c). The ALICE Inner Tracking System (ITS) plays a central role in this effort, it is the first large-area silicon tracker constructed entirely from Monolithic Active Pixel Sensors (MAPS). [...]
