Installation and commissioning of the ME4/2 Cathode Strip Chamber
Since March this year new layers of Muon chambers have been added to CMS on both YE3 endcap disks.
Update from Physics Coordination (2014-04-17)
We have had three important events on the “Higgs front” in the past few days:
⁃ Our H→ττ paper (HIG-13-004) is now accepted for publication by JHEP

Two Higgs or not two Higgs? CMS advances the search for Higgs boson pair production
CMS advances the study of Higgs boson’s self-interaction by searching for Higgs boson pairs decaying into bottom quark–antiquark and tau lepton–antilepton pairs in collisions recorded between 2022 and 2024.
Is the Higgs boson truly elementary?
CMS probes the highest-energy lepton pairs ever recorded to search for hints pointing to a Higgs boson made of smaller constituents.
A glimpse of tomorrow's collider, today
A special test run, with more than twice as many near-simultaneous collisions as usual, allowed CMS to test new methods of tracking and identifying particles, years before the upgraded High-Luminosity LHC comes online.
A messenger of the hottest matter in the Universe
Using Z bosons, the CMS experiment reveals new details of how the Quark-Gluon Plasma drains energy from energetic quarks and challenges current theoretical descriptions.
CMS at ICHEP 2026
The CMS Collaboration announces 28 new results for ICHEP 2026.
Among the highlights are three new results including 2026 data, and several brand new searches.
HGCAL keeps its cool in major testing milestone
One of the largest structures of CMS's future High Granularity Calorimeter (HGCAL) has successfully completed a demanding series of cold tests, marking an important milestone on the road to the High-Luminosity LHC and the next era of particle physics research.
CMS and ATLAS recognise longstanding industrial partner Hamamatsu Photonics K.K.
Hamamatsu Photonics K.K. was announced as the 2026 Industrial Award winner by the ATLAS and CMS Collaborations at a dedicated ceremony on 15 July.
