Breit-wheeler process
WebNov 18, 2024 · Zstar, here, is not the actual ion charge. It is used to test the cumulative ionisation probability for each charge state. The ion is not always ionised (only when U2 < We/Wi) because it is a Monte Carlo approach to particles having different weights. It is true that the order of loops and ifs is not optimal here. 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 …

WebThe advent of laser-driven high-intensity $\\gamma$-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 … WebIn 1934 a pioneering work by Breit and Wheeler [1] proposed for the first time that the collision of two highly energetic photons could lead to the creation of an electron …
