Investigation of charm-quark hadronization in proton–proton collisions
/ Cheng, Tiantian (CCNU, Wuhan, Inst. Part. Phys.)
/ALICE Collaboration
Measurements of different charm-hadron species, particularly the yield ratios as a function of transverse momentum, provide unique insights into heavy-quark hadronization. In this contribution, the recent results of charm production in proton-proton (pp) collisions at √s= 5.02 and 13 TeV, collected during Run 2 by the ALICE experiment, are presented. [...]

The ALICE 3 particle identification systems
/ Gioachin, Giulia (Turin U. ; INFN, Turin)
/ALICE Collaboration
The ALICE Collaboration has proposed a completely new apparatus, ALICE 3, for the LHC Runs 5 and 6. The experiment will enable novel studies of the quark-gluon plasma focusing on low-pT heavy-flavour production, as well as on precise multi-differential measurements of dielectron emission to probe the mechanism of chiral-symmetry restoration and the time-evolution of the QGP temperature.The detector consists of a large pixel-based tracking system covering eight units of pseudorapidity and including a vertex detector mounted on a retractable structure inside the beam pipe.

The ITS3 detector and physics reach of the LS3 ALICE Upgrade
/ Schlepper, Felix (CERN ; Heidelberg U.)
/ALICE Collaboration
During Long Shutdown 3 of the Large Hadron Collider (2026-2028), the ALICE experiment is replacing its innermost three tracking layers with a new detector, the ITS3 (Inner Tracking System 3).It will be based on newly developed wafer-scale monolithic active pixel sensors, which are bent into truly cylindrical layers and held in place by light mechanics made from carbon foam. The unprecedentedly low material budget (0.07% per layer) and proximity of the first ITS3 layer to the interaction point (19 mm) will lead to a factor two improvement in pointing resolutions with respect to the present ITS2 at very low pT (O(100) MeV/c).The pointing resolution of ITS3 for 1 GeV/c primary charged pions is 20 μm and 15 μm in the transverse and longitudinal directions, respectively.After the successful R&D; phase (2019-2023), which demonstrated the feasibility of this innovative detector, the final sensor and mechanics are being developed right now.This contribution will shortly review the conceptual design and the main R&D; achievements, as well as the current activities and road to completion and installation.It concludes with a projection of the improved physics performance, particularly for the heavy-flavour hadrons that will will be reached with the installation of this new detector..

Search for jet quenching in small systems
/ Krizek, Filip (Rez, Nucl. Phys. Inst.)
/ALICE Collaboration
High multiplicity final states of small collision systems, such as proton-proton or proton-nucleus, exhibit some signatures which resemble features associated with QGP formation in heavy-ion collisions, e.g., collective phenomena or enhancement in produced strangeness. At the same time, there is no experimental evidence for QGP-induced jet quenching to date. [...]
