Measurement of W boson particle mass confirms Standard Model of physics and reignites the search for other particles.

Physicists on the CMS experiment announce the most elaborate mass measurement of a particle that is notoriously difficult to study and has captivated the physics community for decades. After an ...

When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the ...

For over a decade, the CMS Collaboration, a large team of researchers based at different institutes worldwide, has been analyzing data collected at the Compact Muon Solenoid, a general-purpose ...

The hugest superconducting solenoid ever built in the world is finally completed. It is formed by five huge modules connected each other and will generate a magnetic field of 4 Tesla, equal to 100.000 ...

A background radiation monitoring system and parameters of colliding beams have been changed at the Compact Muon Solenoid (CMS), one of the large general-purpose particle detectors of the Large Hadron ...

The Compact Muon Solenoid detector is located 100 meters underground on the Franco-Swiss borderer at CERN and collects data from the Large Hadron Collider. The detector has been operational since 2010 ...
