New study of rare B meson decays to two muons
Rare events, such as a total solar eclipse or a supernova explosion, are fascinating and stimulate our imagination.

Jet cones with top flavour
CMS has developed a new method to measure the properties of the top quark with high precision.

Protons that do not break up at the LHC
The processes that are mostly studied at the LHC are caused by energetic collisions where the protons break up into their constituents, the quarks and gluons, which recombine to form composite hadrons.

The Higgs Boson turns 10: Results from the CMS experiment
Exactly ten years ago, on the 4th of July 2012, the ATLAS and CMS experiments announced the discovery of a new particle compatible with the long-sought Higgs boson.

In a detector far, far away: searching for elusive long-lived travellers by tracing pairs of muons
A search for long-lived particles decaying into two muons has been performed by the CMS collaboration. Many scenarios of beyond standard model physics envisage such a possibility, whereby the exotic particles, travel before decaying, a considerable distance which can range from few microns to several kilometres depending on detailed properties. The striking experimental signature of…

Opening up the tau cone in search for new particles
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 existence of additional particles–including new scalar bosons–which could help explain mysteries such as dark matter or the…
