The existence of antimatter is a fundamental aspect of our Universe and is predicted by the laws of quantum physics and symmetry principles. However, the theory does not match the experimental observations. According to our models, we would expect…

The first measurement of the W boson mass (mw) performed by the CMS Collaboration was announced in September 2024. This result has been long-awaited—the first LHC measurement of mW, by the ATLAS Collaboration, was shown nearly 7 years ago. In the…

R&D activities are vital for the ROOT project. A few years ago, we started investigating the evolution of TTree, ROOT’s columnar format with which more than two exabytes of data were written at the LHC: experiments write data, lots of it, to…

One of the conclusions from the ESPPU 2013 process was that CERN should actively engage in the global accelerator-based neutrino program. As a result, CERN became involved in various initiatives, including the DUNE project, and took a leading role…

One of the most fascinating characteristics of particles carrying colour charge, such as quarks and gluons, is their inability to exist as free entities in nature. They are indeed perpetually confined within colour-neutral composite particles known…
