Fabrication and characterization of Triple GEM detectors for HEP experiments / Giri Raj Mohan Sharma ; Dhingra, Nitish (Panjab U.) ; Chauhan, Sushil Singh (Panjab U.) ; Bhatnagar, Vipin (Panjab U.) /CMS Collaboration
Gas Electron Multiplier (GEM) detectors are advanced micro-pattern gaseous devices designed for particle detection in harsh radiation environments. The central feature of GEM detector is a thin metal-clad polymer (usually Kapton) foil chemically etched with a high density of microscopic bi-conical holes, where each hole acts as an individual proportional amplifier.

Highly boosted dielectron identification in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A new technique is developed to identify dielectrons ($ \mathrm{e}^+\mathrm{e}^- $) with Lorentz boost $ \gamma_{\mathrm{L}} > $ 20 that produce one single merged cluster in the electromagnetic calorimeter of the CMS detector. [...]

Study of rare decays in the flavor sector at CMS / Buonsante, Marco (INFN, Bari ; Bari U.) /CMS Collaboration
Rare decays offer a unique window on the flavour structure of the Standard Model, as their strongly suppressed rates make them sensitive to small deviations induced by new physics. In this proceeding, we present CMS Run~3 results on rare decays in proton-proton collisions at $\sqrt{s}=13.6\,\mathrm{TeV}$, including the searches for rare $B_{(s)}^0\to\mu^+\mu^-\mu^+\mu^-$ and $\tau\to3\mu$ decays and the first observation of the $\eta\to\mu^+\mu^-e^+e^-$ decay..

Searches for New Physics at High Object Masses with CMS / Malara, Andrea (Brussels U.) /CMS Collaboration
Searches at high object masses probe both resonant production of new particles and nonresonant distortions of Standard Model spectra. This contribution follows the material presented in the Moriond Electroweak 2026 talk and summarizes recent CMS results in this regime: the Run~2 combination of heavy vector boson searches, the Run~3 search for $W^\prime \to \ell \nu$, the Run~2 dijet angular analysis, and searches for pair-produced dijet resonances in inclusive and $b$-tagged final states. No significant deviation from the SM expectation is observed, and the new results extend the sensitivity of CMS to multi-TeV scales in several benchmark scenarios..

Multiboson and VBS measurements in ATLAS and CMS / Folgueras, Santiago (Oviedo U.) /ATLAS and CMS Collaborations
A review of recent multiboson and vector boson scattering (VBS) measurements from the ATLAS and CMS Collaborations at the LHC is presented. Results are reported from precision diboson cross-section measurements, novel CP-sensitive and polarisation observables in $W\gamma$ production, VBS observations in semileptonic and fully leptonic final states including the first measurements at $\sqrt{s}=13.6\tev$, and observations of triboson processes.

First look at $W^{\pm}W^{\pm}$ and $W^{\pm}Z$ vector boson scattering at $\sqrt{s}$ = 13.6 TeV / Ghimiray, Monika (NCBJ, Swierk) /CMS Collaboration
The measurement of the production cross-section for the $W^{\pm}W^{\pm}$ and $W^{\pm}Z$ channels at $\sqrt{s}=13.6$ TeV is presented using 171 $\mathrm fb^{-1}$ of proton-proton collision data collected with the CMS detector during 2022-2024, in the fully leptonic final states in association with two jets. The electroweak $W^{\pm}Z$ process is observed with a significance of about $7\sigma$, while the electroweak $W^{\pm}W^{\pm}$ signal is established well above $5\sigma$..

Searches for other exotica / Koraka, Charis Kleio (Wisconsin U., Madison) /ATLAS and CMS Collaborations
A review of recent searches for exotic, beyond the Standard Model (BSM) physics signatures, performed by the ATLAS and CMS Collaborations is presented, covering results shown at the 60th Rencontres de Moriond Electroweak session. The searches discussed target unconventional signatures that go beyond the standard paradigm of high-mass resonances and large missing transverse momentum Heavy Neutral Leptons in W boson decays, exotic Higgs decays to pairs of scalars with unequal masses, Soft Unclustered Energy Patterns (SUEPs) in both hadronic and leptonic channels, s-channel production of lepton-enriched semi-visible jets, and a model-independent anomaly detection search in multi-lepton final states.
