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..

Performance of the New CMS-HF Online Radiation Damage Monitoring System / , (Bogazici U.) ; Onel, Yasar (Iowa U.) ; Gulmez, Erhan (Bogazici U.)
The CMS-HF Calorimeter is designed to detect forward going particles. Discovery type events are believed to produce high energy particles going at forward angles. [...]

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. [...]

Search for LFV with tau leptons in the final state / Guzzi, Luca (INFN, Milan Bicocca) /CMS Collaboration
In the Standard Model (SM) lepton flavour numbers are approximately conserved at energies accessible to current experiments, where lepton flavour violation is extremely suppressed. The observation of neutrino oscillations, however, proves that neutrinos are massive particles and allows for additional Lepton Flavour Violating (LFV) processes also at low energies [...]

Searches for New Physics that couple with third generation fermions / D'Amante, Valeria (INFN, Pisa) /CMS Collaboration
The $\tau$ lepton, with a mass of $1776.86\pm0.12$ MeV, is unique in its ability to decay into hadrons and a neutrino. Approximately one third of $\tau$ decays produce an electron or a muon and two neutrinos, denoted as $\tau_e$ and $\tau_\mu$. [...]

Radiation Hard Pixel Sensors for the Phase 2 Upgrade of the CMS Inner Tracker / Steinbrueck, Georg (Hamburg U.) /CMS Collaboration
The Inner Tracker (IT) of the Compact Muon Solenoid (CMS) experiment of the Large Hadron Collider at CERN will be upgraded for the High-Luminosity LHC (HL-LHC). The expected integrated luminosity at the end of the HL-LHC running phase is at least 3000 fb$^{-1}$, corresponding to a 1 MeV neutron equivalent fluence of $\Phi_{\rm eq} = $ 2.6$\times 10^{16}$~cm$^{-2}$ and a total ionizing dose (TID) of 13 MGy at the innermost layer of the IT [...]

Higgs and precision physics at CMS / Mondal, Spandan (Brown U.) /CMS Collaboration
Since the discovery of the Higgs boson in 2012, significant progress has been made in measuring several properties related to the Higgs boson. The large dataset available now facilitates precise measurements of the Higgs boson mass, natural width, couplings, production cross sections, and even differential and fiducial cross sections. [...]
