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.

Dr. Randolf Pohl from the Institute for Physics at Johannes Gutenberg University Mainz (JGU), have successfully conducted experiments on hydrogen atoms which allow testing of the Standard Model of ...
