The observed mass of the Higgs boson is, from the theoretical point of view, unnaturally small. This conundrum is forcing physicists to explore exotic explanations.

The first observation of collider neutrinos at the LHC paves the way for exploring new physics scenarios

On 11 February 2023, we acknowledge the valuable contributions of women and girls to science, technology, engineering and mathematics

Forty years ago today, physicists at CERN announced to the world that they had discovered the electrically charged carrier of the weak force, one of nature’s four fundamental forces

Precise knowledge of luminosity is crucial for both searches for new phenomena and precision measurements of known Standard Model processes

Highlights of the year at CERN, from the record-breaking start of LHC Run 3 to great particle physics results and much more

Simultaneous measurements of rare B-meson decays using the full LHC Run 1 and 2 data samples agree with the predictions of the Standard Model, superseding previous results that had indicated intriguing departures from the 50-year old theory

CMS has now released the complete set of proton-proton data taken from LHC Run 1, including the original findings used in the Higgs boson discovery

The finding will help space- and balloon-based searches for antimatter that may have originated from dark matter
