WebApr 11, 2024 · The advent of laser-driven high-intensity $γ$-photon beams has opened up new opportunities for designing advanced photon-photon colliders. Such colliders have the potential to produce a large yield of linear Breit-Wheeler (LBW) pairs in a single shot, which offers a unique platform for studying the polarized LBW process. In our recent work … The Breit–Wheeler process or Breit–Wheeler pair production is a proposed physical process in which a positron–electron pair is created from the collision of two photons. It is the simplest mechanism by which pure light can be potentially transformed into matter. The process can take the form γ γ′ → e e … See more The photon–photon Breit–Wheeler process was described theoretically by Gregory Breit and John A. Wheeler in 1934 in Physical Review. It followed previous theoretical work of Paul Dirac on antimatter and pair … See more Photon–photon Breit–Wheeler possible experimental configurations Although the process is one of the manifestations of the mass–energy equivalence, as of 2024, the pure Breit–Wheeler has never been observed in practice because of … See more • Two-photon physics See more
