After an eight-week journey, the first HGCAL absorber structure (CE-H1) was delivered to CERN and is ready to be assembled, just 100 metres above where the detector will eventually be located.
The CMS experiment utilises cutting-edge machine learning techniques to search for microscopic, quantum black holes and other exotic objects that evaporate in an instant.
Upon close inspection, the tetraquark family members are consistent with tightly bound diquark pairs
Luigi Marchese wins the prestigious SIF 2025 award for Science Communication, recognising his work on disseminating physics through comic books from the Societa’ Italiana di Fisica “Italian Physics Society”, or SIF.
“I can’t believe such an amazing experiment is right on our doorstep!”
“Wow!”
“Thanks so much for sharing this with us!”
Joel Butler, former CMS Spokesperson (2016-18), has been awarded with the APS 2026 Panofsky Prize in Experimental Particle Physics.
The prestigious prize was announced this morning by the American Physical Society (APS).
The CMS experiment announces new results for the Higgs 2025 conference.
For the Higgs 2025 conference, CMS publishes a number of new results.
The CMS Collaboration announced the 2025 Young Researcher Prize winners during the September 2025 CMS Week. The winners are: Cécile Caillol, Elisabetta Manca, Mario Masciovecchio, Jennifer Ngadiuba!
Using data collected from 2016 to 2023 and cutting-edge machine learning, CMS observes for the first time the creation of a top quark together with a W and a Z boson – a process so rare it occurs only once in a trillion proton-proton collisions!
In the first search of its kind at a particle collider, the CMS experiment looks for partially visible sprays of particles (jets), containing leptons and dark matter using physics-informed machine learning.
