Status of the Fast Interaction Trigger detector of ALICE / Rojas Torres, Solangel (CTU, Prague) /ALICE Collaboration
The Fast Interaction Trigger (FIT) is one of the detectors installed in the ALICE experiment during the second Long Shutdown (LS2) of the LHC to cope with the new collision rates of 50 kHz for Pb-Pb and up to 1 MHz for pp collisions. FIT comprised of the FT0, FV0, and FDD sub-detectors that use Cherenkov and scintillator technologies. [...]

Electromagnetic radiation in pp and Pb--Pb collisions with dielectrons in ALICE / MuraKami, Hikari (Tokyo U., CNS, Saitama) /ALICE Collaboration
The latest ALICE results on low $𝑝_{{\rm T}}$ direct photon measurements via the virtual photon method are presented. Direct photons are measured in Pb–Pb collisions at $\sqrt{s}_{{\rm NN}}$ = 5.02 TeV, and in minimum-bias (MB) and high-multiplicity pp collisions at $\sqrt{s}$ = 13 TeV with LHC Run 2 data. [...]

ALICE ITS3: the first truly cylindrical inner tracker / Kotliarov, Artem (Rez, Nucl. Phys. Inst. ; CTU, Prague) /ALICE Collaboration
During the next LHC Long Shutdown 3 in 2026--2028, the ALICE Collaboration plans to replace the three innermost layers of the current Inner Tracking System (ITS) with truly cylindrical layers, made of wafer-scale, thin ($< 50~\upmu$m), and bent Monolithic Active Pixel Sensors (MAPS) that will be produced with the 65 nm CMOS imaging process. To fabricate the wafer-scale sensors, a technology, called stitching, is utilized to ``stitch'' small reticles and build sensors up to 300 mm in length in a single wafer. [...]

Measurements of HF-tagged jet substructure and energy-energy correlators with ALICE / Mazzilli, Marianna (Houston U.) /ALICE Collaboration
Properties of partonic fragmentation in quantum chromodynamics (QCD) depend on parton flavours in $1\rightarrow2$ splitting processes in parton showers due to the different Casimir factors of quarks and gluons, and to the different masses of light- and heavy-flavour quarks. Heavy-flavour jets provide a unique experimental tool to probe these flavour dependencies. [...]

Recent charmonium measurements in Pb–Pb collisions with ALICE / Sharma, Himanshu (INFN, Padua) /ALICE Collaboration
Charmonia are key probes to study nuclear matter in extreme conditions, like the quark--gluon plasma formed in heavy-ion collisions. At LHC energies, the regeneration process due to the abundantly produced charm quarks was found to considerably affect measured charmonium observables. [...]

Characterization of heavy-quark fragmentation via jets and correlations with ALICE / Kumar, Shyam (INFN, Bari) /ALICE Collaboration
Fragmentation functions are a key component of quantum chromodynamics (QCD) calculations based on the factorisation approach. They are typically determined from the analysis of electron\textendash positron ($\rm e^-e^+$) and electron\textendash proton ($\rm ep$) collision data. [...]

Coherent J/$\psi$ photoproduction and polarization in peripheral Pb-Pb collisions with ALICE / Mallick, Dukhishyam (IJCLab, Orsay) /ALICE Collaboration
Photonuclear reactions are induced by the strong electromagnetic field generated by ultrarelativistic heavy-ion collisions. These processes have been extensively studied in ultraperipheral collisions, in which the impact parameter is larger than twice the nuclear radius. [...]

Search for medium-induced jet quenching effects in small collision systems with ALICE / Ryu, Jaehyeok (Pusan Natl. U.) /ALICE Collaboration
Collisions of small systems show signatures suggestive of collective flow associated with QGP formation in heavy-ion collisions. Jet quenching is also a consequence of QGP formation, but no significant evidence of it in small systems has been found to date. [...]
