🤩 In a first-of-its-kind search at the LHC, CMS probed Higgs boson decays to new light particles that give charged hadrons and muons. The results: such decays, if they occur at all, are limited to less than 0.01% of all Higgs boson decays. Read more: cms.cern/news/hunting-e…
Meet Annabel, Walter and Amal — just a few of this year's CERN summer students working with the CMS experiment — and get an inside look at their incredible experience! 📽️Watch here: youtu.be/pSKtNaNbZ9w
CMS presents its most precise and comprehensive measurement of the Higgs boson yet! 📏 Read more about how combining different studies made this remarkable result possible: cms.cern/news/pieces-pr…
On the hunt for an ungovernable heavy boson 🕵️ CMS investigates Z boson decays which would rebel against the established behavior of lepton-flavor conservation. 👉Read more: cms.cern/news/hunt-rule…
Did you miss the recent ‘Progress in Physics’ article featuring a CMS result on quantum entanglement in top quark–antiquark pairs? Read it on Physics World: physicsworld.com/a/probing-quan…
A novel probe of the Higgs-charm interaction: CMS researchers take a first look at W boson charge asymmetry produced in association with a Higgs boson. 📌Read more: cms.cern/news/cms-measu…
CMS has completed a new Data Acquisition System (DAQ) room! This room is key to increasing the data processing capacity from 2 Tb/s to 50 Tb/s for Run 4 — roughly 500,000 times more than a typical household fibre-optic internet connection. Read more: cms.cern/news/cms-compl…
CMS' Marina Passaseo interviews Barbara Storaci and Sarah Seif El-Nasr about their journey from particle physics at @CERN to working in sports at @UEFA ! 🎙️ Hear how #science gave them confidence on and off the pitch. Watch the full video here: youtu.be/TgSci4JSdaI #sports
An Optical Trigger MotherBoard for the Cathode Strip Chamber that enables communication with another muon detector, the Gas Electron Multiplier. The integrated triggering system enhances muon detection by combining data from both detectors. 🏆 Muon Image of the Month 📸 D. Morse
This is one of the five double disks for each of the two Tracker Endcap Double Disks (TEDD), being built for Hi-Lumi LHC. Each disk is made up of two half-disks or "Dees". Two disks, separated by around 2 cm, form a double disk! 🏆 Tracker Image of the Month 📸 A. Mussgiller
How do you weigh the W boson using hadrons? ⚖️⚛️ For the first time ever at a hadron collider, CMS has managed to do it! Read more: cms.cern/news/how-weigh… #Science
🚀 In hot pursuit of supersymmetry: CMS explores a wide range of final states with boosted particles using a razor-sharp analysis. The result? One of the most comprehensive searches for supersymmetry yet. Read more: cms.cern/news/all-round… #science #Physics
Our kind of biscuit tray — but with hexaboards for the future High Granularity Calorimeter (HGCAL), planned for the Hi-Lumi LHC upgrade. The increased granularity of HGCAL will help better distinguish signals from different particles.⚛️ 🏆 HGCAL Image of the Month 📸 HGCAL team
All credits to CMS! 📸These event displays are visual representations of particle collisions, reconstructed from signals recorded by CMS. As particles pass through detector, they leave traces, which are processed & transformed into these stunning displays by specialised software.
One photon short! CMS breaks new ground by using AI to hunt for exotic Higgs boson decays. ⚛️ Read more: cms.cern/news/one-photo… #science #HiggsBoson #particlephysics
What are conference talks actually like? 🎙️ Listen to CMS' physics coordinator, Roberto Salerno, as he explains how CMS is pushing the boundaries of physics in his talk at the EPS Conference 2025. ⚛️ youtube.com/watch?v=nBbG37…
🤔Could the Higgs boson have a shadowy cousin? CMS is pushing boundaries with #AII in the search for the dark Higgs – a potential link to #darkmatter 😲 👉To find out more about this study, read the physics briefing on our website: cms.cern/news/higgs-bos… #physics #physicsnews
This tray is part of the CMS MIP Timing Detector (MTD), to be installed around the Tracker for the Hi-Lumi LHC upgrade. With ~35 ps time resolution, it will help CMS maintain event reconstruction accuracy even with 5x more collisions. 🏆MTD Image of the Month 📸A. Benaglia
✨Top Quark: The Lone Traveller✨ In the latest episode of the top quark saga, CMS reveals for the first time how a single top quark is produced in a mode called "t-channel" in a new, uncharted territory: 5.02 TeV! Read the briefing for more: cms.cern/news/top-quark…
The 2025 European Physical Society Conference on High Energy Physics took place in Marseille from 7-11 July 2025, and CMS was there, represented by many scientists & posters! Can our scientists explain their research in less than a minute? Let’s find out: youtu.be/_DuzMO4hKP0?si…
