New ATLAS measurement of lepton flavour universality, a key feature of the Standard Model, in decays of the W boson is more precise than all previous measurements combined

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

Physicists at the ATLAS experiment are on the hunt for new, long-lived particles to help explain several outstanding mysteries of our Universe

The LHCb results strengthen hints of a violation of lepton flavour universality

The bounds are some of the tightest yet on the existence of third-generation leptoquarks

A new ATLAS measurement of a key feature of the Standard Model known as lepton flavour universality suggests that a previous discrepancy measured by the LEP collider in W boson decays may be due to a fluctuation

For the first time, LHCb uses beauty baryons to test this key principle of the Standard Model

Recent results from CMS explore third-generation leptoquarks: hypothetical particles that combine the properties of leptons and quarks

New results from LHCb suggest that B+mesons decay to muons about 25% less often than they decay to electrons
