The ATLAS and CMS collaborations have both observed the simultaneous production of four top quarks, a rare phenomenon that could hold the key to physics beyond the Standard Model

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

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

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

In their first Run 3 results, the ATLAS collaboration measured two Standard Model processes: the production of Z bosons and top-quark pairs

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

The CAPP axion haloscope at the CAST experiment has hunted for axions from the Milky Way’s “halo” of dark matter, and has narrowed down the theoretical space in which to look for these hypothetical particles

The decay width is linked to the particle’s lifetime and if found to deviate from its predicted value could indicate the presence of new physics

CMS measured the top-quark pair production cross section
