The CMS detector, illustrated in Fig. 1, is centred around the largest and highest granularity silicon tracker ever built, including around twenty thousand detector units structured in thin cylindrical layers that extend over nearly 6 metres along…
“The important thing”, says Einstein, “is not to stop questioning”, and we, as humans, never have. What is it all made up of? How does it fit together? We’ve been yearning to answer these questions for aeons, with our collective efforts…
Could there be more particles like the Higgs boson? For the first time, the CMS experiment has searched for the decay of the Higgs boson into two more Higgs-boson-like particles with unequal masses.
Some theories suggest that the Higgs boson…
CMS sets the world’s most stringent limits on B⁰ and B⁰ₛ decays into four muons.
After examining the Run 3 dataset collected between 2022 and 2024, the CMS experiment has established the most stringent limits to date on the extremely rare decays of…
CMS pushes the sensitivity frontier towards a measurement of the rare Higgs boson decay into a Z boson and a photon
The 2012 discovery of the Higgs boson at CERN by CMS and ATLAS was a landmark achievement in the world of particle physics - but it…
CMS sees evidence of the Upsilon meson decaying into two tau leptons for the first time at a hadron collider
Beyond our best current understanding of particle physics, encapsulated in the standard model, various theoretical models predict the…
