Charm production: Constraint to transport models and charm diffusion coefficient with ALICE / Völkl, Martin (Heidelberg U.) /ALICE Collaboration
New measurements of D mesons with the ALICE detector, interpreted with theoretical models, can give additional information about the spatial diffusion coefficient, a characteristic of the QGP medium. The relevant ingredients to the models can be assessed by comparing the predictions with diverse measurements of charmed hadrons. [...]

Feasibility study of the Alice fixed-target experiment with HL-LHC lead ion beams based on crystal-assisted beam Halo splitting / Patecki, Marcin (Warsaw U. of Tech. (main)) ; Monikowska, Marta (Warsaw U. of Tech. (main))
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) is the world's largest and most powerful particle accelerator, colliding beams of protons and lead ions at energies up to 7 ZTeV. ALICE is one of the detector experiments optimized for heavy-ion collisions.A fixed-target experiment in ALICE is considered to collide a portion of the beam halo, split using a bent crystal, with an internal target placed a few meters upstream of the detector.

Test beam performance of a novel RICH detector with timing capabilities for the future ALICE 3 PID system at LHC / Mazziotta, M N (INFN, Bari) ; Congedo, L (INFN, Bari) ; De Robertis, G (INFN, Bari) ; Di Mauro, A (CERN) ; Licciulli, F (INFN, Bari) ; Lorusso, L (INFN, Bari ; Bari U. ; Bari Polytechnic) ; Martinengo, P (CERN) ; Nappi, E (INFN, Bari) ; Nicassio, N (INFN, Bari ; Bari U. ; Bari Polytechnic) ; Panzarini, G (INFN, Bari ; Bari U. ; Bari Polytechnic) et al.
The ALICE Collaboration is proposing a completely new apparatus, ALICE 3, for the LHC Run 5 and beyond. A key subsystem for charged particle identification will be a Ring-Imaging Cherenkov (RICH) detector consisting of an aerogel radiator and a photosensitive surface based on Silicon Photomultiplier (SiPM) arrays in a proximity-focusing configuration.

Applications of CMOS Technology at the ALICE Experiment / Colella, Domenico (Bari Polytechnic ; Western Cape U.) /ALICE Collaboration
Monolithic Active Pixel Sensors (MAPS) combine the sensing part and the front-end electronics in the same silicon layer, making use of CMOS technology. Profiting from the progresses of this commercial process, MAPS have been undergoing significant advances over the last decade in terms of integration densities, radiation hardness and readout speed.

ALICE ITS3: how to integrate a large dimension MAPS sensor in a bent configuration detector / Colella, Domenico (Bari Polytechnic) /ALICE Collaboration
The ALICE Collaboration is developing a novel vertexing detector to extend the heavy-flavour physics programme of the experiment during Run 4 by improving the pointing resolution of the tracking, particularly at low transverse momentum. It will be a detector with three truly cylindrical layers based on thin wafer scale MAPS, reaching less than 0.07% X/X0 per layer and with the innermost layer located as close as 19 mm to the interaction point.

Performance and operational experience of ALICE ITS2 in LHC Run 3 / Liu, J (Liverpool U.) /ALICE Collaboration
The ALICE experiment underwent major upgrades during the LHC Long Shutdown 2 (2019–2021), including the installation of the new Inner Tracking System (ITS2). ITS2 comprises seven layers with 12.5 billion pixels covering 10 m^2, based on the ALPIDE CMOS Monolithic Active Pixel Sensors (MAPS), which offer a spatial resolution of approximately 5 µm. [...]

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.
