Photon Collider Theoretically Produces Matter

Facebook X LinkedIn Email
Producing matter from light via two-photon collision was originally proposed in 1934, but there has never been a viable experimental method to prove this fundamental prediction of quantum electrodynamics – until now. The 80-year-old theory, proposed by John Wheeler and Gregory Breit, says that because annihilating electron-positron pairs produces two or more photons, colliding photons should produce electron-positron pairs. Experimental verification would not only help validate QED, but also could be applied to the study of elastic photon-photon scattering and quark resonances,...Read full article
