WebAug 18, 2024 · Abstract High-energy photons can decay to electron-positron pairs via the nonlinear Breit-Wheeler process when colliding with an intense laser pulse. The energy spectrum of the produced particles is broadened because of the variation of their effective mass in the course of the laser pulse.
WebThe theory of the Breit-Wheeler process says it should be possible to turn light into matter by smashing two particles of light (photons) together to create an electron and a positron. However, past attempts to do this have required the addition of other high-energy particles. WebBreit-Wheeler process in band gapped graphene layers at a much lower energy scale has recently been discussed [32]. In the current paper, we propose an alternative approach …
WebMar 5, 2024 · 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 − where γ and γ′ are two light quanta … WebAug 10, 2024 · The process involves, as the collider's name suggests, accelerating ions - atomic nuclei stripped of their electrons. Because electrons have a negative charge and protons (within the nucleus) have …
WebJan 7, 2016 · Direct production of electron-positron pairs in two-photon collisions, the Breit-Wheeler process, is one of the basic processes in the universe. However, it has never been directly observed in the laboratory because of the absence of the intense γ -ray sources. Laser-induced synchrotron sources emission may open a way to observe this process.
