CMS track reconstruction performance and tracking developments during Run 3 / Bruschini, Davide (INFN, Pisa ; Pisa, Scuola Normale Superiore) /CMS Collaboration
The precise and efficient reconstruction of charged particle tracks is crucial for the success of the CMS experiment at the LHC. Prior to the start of LHC Run 3 in 2022, the first layer of the Tracker Barrel Pixel subdetector was replaced to cope with the high pileup environment, and significant upgrades were made to the track reconstruction algorithms.

Upgrade of the CMS muon system / Calzaferri, Simone (INFN, Pavia) /CMS Collaboration
This contribution illustrates the four different detector technologies used in the muon spectrometer of the Compact Muon Solenoid (CMS) experiment, installed on the Large Hadron Collider (LHC), and their future upgrades. These have the aim to cope with the scheduled increase of instantaneous luminosity of the LHC in the so called $\mbox{High-Luminosity}$ LHC phase..

Results and Perspectives on Multi-Parton Interactions with CMS / Ascioti, Maria Elena (INFN, Perugia ; Perugia U.) /CMS Collaboration
This contribution covers recent CMS experiment studies at the LHC, including the first direct observation of Double Parton Scattering (DPS) in same-sign WW boson production at $\sqrt{s} = 13$ TeV. Interest in DPS has shifted to flavour physics due to higher production cross-sections and better detector performance, enabling CMS to rival experiments like LHCb. [...]
