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. [...]

First results on the final readout chip for the High-Luminosity LHC upgrade of the CMS Inner Tracker / Grippo, Michael (INFN, Turin ; Turin U.) ; Bartosik, Nazar (INFN, Turin) ; Demaria, Natale (INFN, Turin) ; Luongo, Fabio (INFN, Turin ; Turin U.)
The CMS Readout Chip (CROC) is a 65 nm CMOS hybrid pixel readout chip for the High-Luminosity LHC upgrade of the CMS Inner Tracker. The chip has been developed by the CERN RD53 Collaboration in order to withstand radiation doses up 10 MGy and hit rates up to 3 GHz cm$^{-2}$ at pileup 200 on the innermost tracking layer. [...]

Measurement of the differential Higgs boson production cross sections in ATLAS and CMS experiments / Mohammadi, Abdollah (Wisconsin U., Madison) /ATLAS and CMS Collaborations
A comprehensive set of studies has been conducted to measure the fiducial differential cross sections of Higgs boson production by the ATLAS and CMS experiments. These analyses are based on proton-proton collision data collected by both experiments at the CERN LHC, with a center-of-mass energy of 13 TeV. [...]

Performance of planar pixel modules for the CMS Phase-2 Inner Tracker / Raciti, Bianca (Hamburg U.) /CMS Collaboration
During the Long Shutdown 3, the CMS pixel detector will be replaced to operate during the High Luminosity LHC \mbox{(HL-LHC)} running phase. Hybrid pixel modules of the new tracking detector will have to fulfill stringent requirements to operate in an extremely harsh radiation environment and cope with the high data readout rate. [...]

3D silicon pixel sensors for the CMS experiment tracker upgrade / Zuolo, Davide (Colorado U.) /CMS Collaboration
The upgrade program of the CMS experiment in view of the LHC High Luminosity phase (HL-LHC) includes a replacement of the silicon pixel tracker. This is necessary to guarantee the same tracking performance of the current detector under harsher operating conditions, including higher radiation fluences and hit rates. [...]

Di-Higgs searches at CMS / Fontana Santos Alves, Bruno Afonso (Ecole Polytechnique) /CMS Collaboration
The production of Higgs boson pairs (HH) at the LHC is the main handle for the measurement of the Higgs boson interaction with itself and is thus a fundamental test of the Standard Model theory as well as for determining the Higgs potential. The most recent results from the CMS Collaboration on measurements of nonresonant HH production using different final states, and their combination using the data set collected by the CMS experiment at a centre of mass energy of 13 TeV, will be presented..

EFT interpretations in the Higgs sector at the CMS Experiment / Guzel, Ahmet Oguz (Louvain U.) /CMS Collaboration
The search for new physics beyond the Standard Model continues to be a focal point in contemporary particle physics research. Despite exhaustive direct searches at the Large Hadron Collider yielding no definitive evidence of new particles, the scientific community is propelled towards indirect search methodologies. [...]

Heavy-flavour tagging at the CMS experiment / Zaza, Angela (INFN, Bari ; Bari U.) /CMS Collaboration
At the CMS experiment, the identification of heavy-flavour jets, i.e., jets originating from bottom and charm quarks, is crucial for many standard model (SM) measurements, mostly involving the top quark and the Higgs boson, and searches for new physics. The CMS Collaboration developed extremely powerful jet tagging algorithms based on state-of-the-art deep learning methods, which will be illustrated in this contribution. [...]
