“…It is important to note that, under resonance conditions (21), the resonant energies of the positron and electron for each reaction channel are determined by different physical processes: the external field-stimulated Breit-Wheeler process (27) and the Compton external field-stimulated effect (34). At the same time, the energies of the electron-positron pair are related to each other by the general law of the conservation of energy.…”

“…It should be noted that, in Equation ( 38), we neglected a small correction term |l|ω/ω i 1. Taking into account Equations ( 27) and (34), as well as the law of conservation of energy (38) for Channels A and B, we obtained the following equations relating the outgoing angles of the positron and electron:…”

“…The process of electron-positron pair production by two gamma quanta was first considered by Breit and Wheeler [32]. Currently, there is a significant number of works devoted to the study of the Breit-Wheeler process in an external electromagnetic field (see, for example, [33][34][35][36][37][38][39][40][41][42][43][44]). It should be noted that a distinction should be made between the external field-stimulated Breit-Wheeler process (a first-order process with respect to the fine structure constant) and the external field-assisted Breit-Wheeler process (a second-order process with respect to the fine structure constant).…”

The resonant external field-assisted Breit–Wheeler process (Oleinik resonances) for strong electromagnetic fields with intensities that are less than the critical Schwinger field that has been theoretically studied. The resonant kinematics were studied in detail. The case of high-energy initial gamma quanta and emerging ultrarelativistic electron–positron pairs was studied. The resonant differential cross section was obtained. The generation of narrow beams of ultrarelativistic positrons (for Channel A) and electrons (for Channel B) was predicted with a probability that significantly exceeded the corresponding nonresonant process.

“…Additionally, it is pointed out that the pair productions in the linear BW process can dominate over ones in the NBW process when a laser pulse with a peak intensity 10 22 Wcm −2 propagates through an overdense plasma channel. Such an interaction scenario induces the relativistic transparency and the coupled NLC, NBW and linear BW processes [135,136]. Therefore, the effects of γ-photon polarization could be no longer negligible in the dynamics of QED plasmas as the yield and kinematics of linear BW pairs have remarkable dependence on the photon polarization [137].…”

High-energy spin-polarized electron, positron, and γ-photon beams have many significant applications in the study of material properties, nuclear structure, particle physics, and high-energy astrophysics. Thus, efficient production of such polarized beams attracts a broad spectrum of research interests. This is driven mainly by the rapid advancements in ultrashort and ultraintense laser technology. Currently available laser pulses can achieve peak intensities in the range of 10 22 − 10 23 Wcm −2 , with pulse durations of tens of femtoseconds. The dynamics of particles in laser fields of the available intensities is dominated by quantum electrodynamics (QED) and the interaction mechanisms have reached regimes spanned by nonlinear multiphoton absorbtion (strong-field QED

“…Among those proposals, the γγ collider is designed either with GeV-energy photons from bremsstrahlung inside a high-Z target and keV-energy partner photon from laser-target radiation or X-ray free-electron laser [24,30,32], or with two same MeV γ-photon sources from laser-driven synchrotron or nonlinear Compton scattering [8,[25][26][27]29]. Moreover, the dominated LBW process is studied in laser-driven plasmas [33,34], and the quasiparticle-hole pair production in gapped graphene monolayers can be analogous to the LBW process [35]. However, above proposals mainly focus attention on the large pair yield, but generally ignore the inherent spin effects of scattering particles.…”

Laser-driven brilliant controllable polarized γ-photon sources open the way for designing compact γγ collider, which enable the large yield of linear Breit-Wheeler (LBW) pairs in a single shot and thus provide an opportunity for the investigation of polarized LBW process. In this work we investigate the polarization characteristics of LBW pair production via our developed spin-resolved binary collision simulation method. Polarization of γphotons modifies the kinematics of scattering particles and induces the correlated energy-angle shift of LBW pairs, and the latter's polarization characteristic depends on the helicity configures of scattering particles. Our method confirms that the polarized γγ collider with an asymmetric setup can be performed with currently achievable laser facilities to produce abundant polarized LBW pairs, fulfilling the detection power of polarimetries. The precise knowledge of polarized LBW process is in favor of the calibration and monitor of polarized γγ collider, and could enhance the opacity of γ-photons in high-energy astrophysical objects to exacerbate the inconsistency between some observations and standard models.
