The CMS Collaboration announces more than 40 new results for Moriond 2025.

In Higgs physics, following a comprehensive research program aimed at characterizing the Higgs boson by measuring its properties and interactions across various decay and production channels, CMS has performed an extensive combination of these measurements. The results include detailed interpretations and constraints on BSM theories. A detailed interpretation within the SMEFT framework is also performed, offering a model-agnostic approach to indirectly probing BSM physics.

CMS presents as well the first combined measurement of VBS across multiple channels, achieving a significant improvement in precision. With the expected significance exceeding 5σ for some of the key processes, the results confirm SM predictions and provide enhanced sensitivity to new physics, marking a major milestone in VBS studies.

A pioneering search is presented for displaced multi-muon resonances in Run 3 using the high-rate Scouting data stream, based on trigger-level reconstruction. Another search explores previously inaccessible low-mass and displaced dimuon signals. The results set the strongest constraints yet on long-lived dark photon models, advancing new physics searches.

Another highlight are the new studies on soft unclustered energy patterns (SUEPs) using both Scouting and standard data streams and investigating VH and gluon-fusion production modes. Novel techniques, including boosted event frame analysis and track-based observables, greatly enhance sensitivity. These searches set the strongest constraints to date on SUEP models, excluding key parameter ranges in Hidden Valley scenarios.

Here is a list of all our results as they are being presented at the conference. Details of the papers and briefings will also be added throughout the conference.
