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 ...

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 ...

The magnetic moment of the muon is an important precision parameter for putting the standard model of particle physics to the test. After years of work, the research group led by Professor Hartmut ...
