Radical photon concept may rewrite usual style of particle physics

If photons possess extra quantum states than anticipated, it could overhaul our figuring out of all particle physics – and now physicists have recognized a option to take a look at this radical concept in an experiment.

Certain fundamental debris have a assets known as spin. For debris of sunshine, or photons, spin can also be in one in every of two doable states, which manifests as the sunshine being polarised in one in every of two instructions. But what if photons had extra choices – what in the event that they…
