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.
This discovery takes us back to the events occurring in our early…
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…
In a recent result, the CMS experiment has combined a comprehensive set of searches for the production of not one but two Higgs bosons – the result is a significant step towards observation of this elusive process, and constitutes a legacy of…
The Higgs boson is deeply connected to the mechanism that generates the masses of elementary particles. In the Standard Model (SM), which describes the properties of all elementary particles and the interactions among them, the Higgs boson…
CMS scientists discover some of the rarest collisions that the LHC can produce – such as the scattering of light by light – and learn more about the quantum nature of electromagnetism, search for new particles, and much more.
In everyday life…
Detailed study of collisions producing top quarks reveals discrepancy with respect to theoretical predictions.
The CMS collaboration has preliminarily reported an unexpected effect in interactions involving top quark pairs. These results…
