An unexpected behavior in a particle decay seems to disagree with the predictions of the Standard Model, despite its high ...

Mystery no more Artist’s conception of the magnetic moment of the muon – a sub-atomic particle similar to, but heavier than, the electron. More than half a century of measurements of that fundamental ...

The standard model of particle physics is often illustrated as a simple grid showing the 17 basic particles (shown above). But an alternative way of visualising it reveals the complex rules that ...

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an experiment.
