Search for Higgs boson pair production with one associated vector boson at CMS / Asawatangtrakuldee, Chayanit (Chulalongkorn U.) /CMS Collaboration
A search for Higgs boson pair production (HH) associated with a vector boson V (W or Z boson) is presented. The search is based on 138 ${\rm fb}^{-1}$ of proton-proton (pp) collisions at a center-of-mass energy of 13 TeV, collected with the CMS detector at the LHC. [...]

Searches for new physics in CMS in events with jets, leptons and photons in the final state / Hart, Andrew Evan (Rutgers U., Piscataway) /CMS Collaboration
Many new physics models, e.g., compositeness, extra dimensions, extended Higgs sectors, supersymmetric theories, and dark sector extensions, are expected to manifest themselves in final states with jets, leptons, and photons. This talk presents searches in CMS for new phenomena in these final states, focusing on the recent results obtained using the full Run 2 data set collected at the LHC..

Higgs boson cross section measurements at CMS / Camaiani, Benedetta (INFN, Florence ; Florence U.) /CMS Collaboration
Inclusive and differential measurements of the Higgs boson production cross section are important tools to test the standard model expectations and to probe physics beyond the standard model. This review summarizes recent Higgs boson cross section measurements, obtained in proton-proton collision data, recorded by the CMS experiment at the CERN LHC during Run 2 at $\sqrt{s}=13$ TeV..

Searches for electroweak SUSY and compressed SUSY spectra from CMS / Kaur, Harjot (Panjab U.) /CMS Collaboration
A wide variety of searches for Supersymmetry have been performed by experiments at the Large Hadron Collider. In this talk, we focus on searches for electroweak production of Supersymmetric particles and searches for Supersymmetric particles in compressed spectra.The results are obtained from the proton-proton collision data with luminosity up to 138 fb-1 at the center of mass energy of 13 TeV collected during the LHC Run 2..

The Phase-2 Upgrade of the CMS Outer Tracker / Marton, Krisztina (Budapest, RMKI) /CMS Collaboration
The Large Hadron Collider at CERN will undergo a major upgrade in the Long Shutdown 3 from 2026 to 2028. The High Luminosity LHC is expected to deliver peak instantaneous luminosities up to 7.5E34/cm2/s and an integrated luminosity in excess of 3000/fb in the following ten years of operation. [...]

Multi-differential measurement of the dijet cross section in proton-proton collisions at $\sqrt{s} = 13\,TeV$ / Kosmoglou Kioseoglou, Polidamas Georgios (Ioannina U.) /CMS Collaboration
A measurement of the dijet production cross section is reported based on an integrated luminosity of $36.3\ fb^{-1}$ of proton-proton collision data collected in 2016 at $\sqrt{s} = 13\ TeV$ by the CMS detector at the CERN LHC. Jets are reconstructed with the anti-kT algorithm for distance parameters of $R = 0.4$ and $R = 0.8$ and differential cross sections are measured as a function of the kinematic properties of the two jets with largest transverse momenta $p_T$.

Observation of $\gamma\gamma\to\tau\tau$ production in PbPb collisions with the CMS experiment / Jana, Pranati (Indian Inst. Tech., Madras) /CMS Collaboration
Ultraperipheral lead-lead collisions produce very large photon fluxes that permit fundamental quantum-mechanical processes to be observed and studied. The first measurement of $\tau$ lepton pair in ultraperipheral PbPb collisions at $\sqrt{s_{_{\mathrm{NN}}}} =$ 5.02 TeV with data collected by CMS during the LHC Run 2 will be presented. [...]

Exotic production and decays of the 125 GeV Higgs - CMS / Das, Pallabi (Princeton U.) /CMS Collaboration
The Higgs boson was discovered more than ten years ago by the LHC experiments, CMS and ATLAS. Following the discovery, the experiments have focussed on measuring the Higgs boson properties to ascertain its agreement with the predictions from the Standard Model of particle physics. [...]

Searches for additional scalars with two photons in the final state at CMS / Tao, Junquan (Beijing, Inst. High Energy Phys.) /CMS Collaboration
Although the Higgs boson discovered at the LHC is so far compatible with the Standard Model Higgs boson within the experimental uncertainties, there is still room for extensions of the Standard Model. Some beyond Standard Models, such as the Two Higgs Doublet Model and the Next-to-Minimal Supersymmetric Standard Model, can predict additional Higgs bosons with rich and interesting phenomenologies.
