Particles known as tensor mesons are created when high-energy photons interact. These mesons have now been proposed to have a larger effect on photon behavior than previously thought, and provide a ...

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.
