CERN Accelerating science

CMS successfully carried out key tests for the lifting system needed in the construction of Hi Lumi CMS during the end of year stop 2025/2026.

The CMS Collaboration reports the first measurement of coherent ϕ meson photoproduction, establishing a powerful new tool to explore the dense nuclear matter in the transition regime from perturbative to nonperturbative QCD.

Anadi Canepa has been elected the new CMS Spokesperson 2026 - 2028. Florencia Canelli will join Hafeez Hoorani as Deputy Spokesperson.

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).
