Search for BSM Physics in High-Mass Diphoton Events at CMS / Kamble, Samadhan (Indian Inst. Tech., Madras) /CMS Collaboration
We present the results from an extensive search for BSM particles in `high-mass diphoton events', a distinctive phase-space indicative of various SM extensions such as Supersymmetry, extra dimensions, and non-minimal Higgs sectors. The searches for both spin-0 and spin-2 particles in resonant as well as non-resonant scenarios were carried out using the full luminosity of the LHC Run-II in proton-proton collisions at $\sqrt{s}$ = 13 TeV with the CMS detector.

Higgs boson production cross section and couplings in the W boson pair decay channel in pp collisions at $\sqrt{s}= 13$ TeV with the CMS detector / Dash, Ganapati (Indian Inst. Tech., Madras) /CMS Collaboration
The production cross sections of the Standard Model Higgs boson decaying into a pair of W bosons have been measured in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis targets Higgs bosons produced through gluon-gluon fusion, vector boson fusion, and in association with a vector boson. [...]

Rare $b \rightarrow sll$ decays at 13 $TeV$ by CMS Detector / Nayak, Samarendra (Bhubaneswar, NISER) /CMS Collaboration
Recent results on the rare $b \rightarrow sll$ decays are presented by the CMS experiment at 13 $TeV$. The individual branching fraction results of $B^{\pm} \rightarrow K^{\pm}\mu^{+}\mu^{-}$ and $B^{\pm} \rightarrow K^{\pm}e^{+}e^{-}$ decays are shown along with the lepton flavor universality (LFU).

Search for Supersymmetry in single lepton events and reinterpretation in the pMSSM-19 framework / Engelke, Frederic (Aachen, Tech. Hochsch.) /CMS Collaboration
Results are presented from a search for supersymmetry in events with a single electron or muon, and multiple hadronic jets. The data correspond to a sample of proton-proton collisions at $\sqrt{s}=13$ TeV with an integrated luminosity of $138 \ \text{fb}^{-1}$, recorded by the CMS experiment at the LHC. [...]

Measurement of the ttH production cross-section in multi-leptonic final states in pp collisions at a centre-of-mass energy of 13 TeV with the CMS detector / Ameen, Mohammad Mobassir (Indian Inst. Tech., Madras) /CMS Collaboration
The Yukawa coupling of the Higgs boson to the top quark is a pivotal parameter in the Standard Model, providing insights into fundamental particle interactions. This coupling is investigated through the production processes of Higgs bosons in association with top quarks, including tH and ttH. [...]

Searches for heavy neutral leptons with machine learning at the CMS experiment / Knolle, Joscha (Gent U.) /CMS Collaboration
Two recent searches for heavy neutral leptons (HNLs) performed with proton-proton collision data recorded at 13 TeV by the CMS experiment are presented. A prompt search in the trilepton final state analyses events with exactly three charged leptons originating from the primary proton-proton interaction vertex, targeting HNL masses between 10 GeV and 1.5 TeV.

Radiation and magnetic field qualification of LVPS - a unified 12V DC power source for the CMS detector. / Stachon, Krzysztof (Zurich, ETH) ; Dissertori, Gunther (Zurich, ETH) ; Gadek, Tomasz (Zurich, ETH) ; Lustermann, Werner (Zurich, ETH) /CMS Collaboration
Efforts aiming at consolidating the powering for the CMS detector have led to the development of a Low Voltage Power Supply (LVPS). The LVPS converts 380 V DC to 12 V DC, suitable for powering the widely used bPOL12V point-of-load DC-DC converter. [...]

Data transmission performance and characterization of TEPX disks of the CMS Phase-2 Inner Tracker / Bilandzija, Filip (Zurich U.)
Before starting the High-Luminosity LHC phase, the CMS detector will be substantially upgraded to cope with the significant increase in instantaneous and integrated luminosity. The entire CMS tracking detector will be replaced, and the new detector will feature increased radiation hardness, higher granularity, and the capability to handle higher data rates and longer trigger latency.

Measurements of the t$\Bar{\text{t}}$H+tH production at CMS / Marchegiani, Matteo (Zurich, ETH) /CMS Collaboration
Following the observation of the Higgs boson at the LHC, the high precision measurements of its properties and the search for its production in various final states have become crucial to test the validity of the standard model. The production of the Higgs boson in association with a top quark and antiquark pair (t$\Bar{\text{t}}$H) is a direct probe of the interaction between the boson and the top quark, providing access to the top-Higgs Yukawa coupling. On the other hand, the production of the Higgs boson in association with a single top quark (tH) is sensitive to the sign of this coupling. The importance of a precise measurement of the top Yukawa coupling stems from its dominant role in the stability of the electroweak vacuum. The latest measurements of the t$\Bar{\text{t}}$H and tH production cross section performed by the CMS collaboration with proton-proton collisions at $\sqrt{s}=$~13 TeV in final states with a Higgs boson decaying to a pair of photons, multiple charged leptons or a bottom quark and antiquark pair are presented..

HNLs at CMS / Lunerti, Leonardo (INFN, Bologna) /CMS Collaboration
The discovery of neutrino oscillations suggests non-zero masses for active neutrinos, which may result from the presence of massive sterile neutrinos, or heavy neutral leptons (HNLs). The most recent searches for HNLs at the CMS experiment are presented. [...]
