Predicting the numerical value of the magnetic moment of the muon is one of the most challenging calculations in high-energy physics. Some physicists spend the bulk of their careers improving the ...

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.

Quantum electrodynamics (QED) is the most rigorously tested quantum field theory of the standard model of particle physics 1. It describes the fundamental electromagnetic interactions of particles and ...
