Steven Weinberg’s iconic paper, A Model of Leptons, was published in 1967 and determined the direction for high-energy particle physics research

Top marks for the Standard Model as LHC experiments ATLAS and CMS study the subtle behaviour of the heaviest particle

The LHCb experiment finds intriguing anomalies in the way some particles decay

The LHCb collaboration has presented a new measurement of a rare particle decay, providing another strong confirmation of the Standard Model

Do recent discoveries mean there’s nothing left? Find out what the future holds for theoretical physics in our final In Theory series installment

The LHCb experiment has measured decays of B mesons that have shown deviations from the predictions of the Standard Model

The particles, known as the Xi_b'- and Xi_b*-, were predicted to exist by the quark model but had never been seen before

At the Moriond conference CMS presented the best constraint yet of the Higgs boson “width”, a parameter that determines the particle’s lifetime

The ATLAS experiment at CERN has found evidence for the Higgs boson decaying to two tau particles

When you've got a discrepancy in the data, it might be time for theory and experiment to collaborate

A standing stone outside the CERN Control Centre neatly sums up our understanding of the universe

Objects as large as a planet or as small as a photon can have the property of spin. Spin is also the reason we can watch movies in 3D.
