Measurement of jet track functions in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
Measurements of jet substructure are key to probing the energy frontier at colliders, and many of them use track-based observables which take advantage of the angular precision of tracking detectors. [...]

Exploring the DGLAP resummation in the JIMWLK Hamiltonian / Armesto, Néstor (Santiago de Compostela U., IGFAE) ; Kovner, Alex (Connecticut U. ; Darmstadt, EMMI ; CERN) ; López-Pardo, Víctor (Santiago de Compostela U., IGFAE)
We explore the recently derived equation that resums DGLAP corrections to the JIMWLK Hamiltonian in the simplified setting of the SU(2) gauge theory. [...]

Gas gaps and chambers quality control of improved resistive plate chambers (iRPC) / Ali, Mohammad Ahammad (Dundee U.) /CMS Collaboration
In preparation for the Phase-II upgrade for the High-Luminosity LHC program, 72 improved Resistive Plate Chambers (iRPC) will be installed in the third and fourth endcap disks of the Compact Muon Solenoid detector during the annual technical stop 2024. This new generation of RPC detectors will operate in a low-angle momentum (extending RPC coverage from pseudorapidity \(\lvert \eta \rvert\) = 1.9 to 2.4), in a high radiation environment, and will bring a better space and time resolution for this challenging region. [...]

Novel ideas for CMS L1 trigger in HL-LHC using RPC ultimate timing performance / Cabrera Mora, Andres Leonardo (Andes U., Bogota) /CMS Collaboration
The CMS RPC system has been upgraded for Phase-2 with two major projects. First is the comprehensive redesign of the Link System connecting the Front-End Boards (FEBs) of existing CMS RPC chambers to the trigger processors, which leads to the full exploitation of the intrinsic time resolution of 1.6 ns.
