High-energy photon-photon collisions produce matter-antimatter pairs (electrons and positrons) via the Breit-Wheeler process, a prediction of quantum electrodynamics that is well-supported by theoretical models and confirmed by recent collider experiments.
The retrieved literature consistently supports the claim that high-energy photon-photon collisions produce matter-antimatter pairs via the Breit-Wheeler process. Multiple papers discuss theoretical formulations, laser-driven experimental setups, and recent collider measurements (such as those at the LHC/CMS) that confirm the Breit-Wheeler process in agreement with quantum electrodynamics predictions. No papers refute the claim.
