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.

Five years after the first evidence that heavy metal hits the top quark, CMS now observes the clash of two titans with higher precision at unprecedented energy.

The CMS Collaboration is proud to announce the recipients of the 2024 Industry and Partner Awards, which recognise the vital contributions of our partners in advancing the experiment's capabilities.
