“…to raise their energies, giving better access to Higgs physics [970]. Some recent work has begun a program of studying treelevel processes, again in circularly polarised, monochromatic plane waves and again investigating Higgs production [971,972,973], as well as kaon decay, CPT symmetry violation [974], Z-boson production [975] and electron-neutrino scattering [976]. There is clearly scope for updating such investigations to include progress made in recent years.…”

Upcoming and planned experiments combining increasingly intense lasers and energetic particle beams will access new regimes of nonlinear, relativistic, quantum effects. This improved experimental capability has driven substantial progress in QED in intense background fields. We review here the advances made during the last decade, with a focus on theory and phenomenology. As ever higher intensities are reached, it becomes necessary to consider processes at higher orders in both the number of scattered particles and the number of loops, and to account for non-perturbative physics (e.g. the Schwinger effect), with extreme intensities requiring resummation of the loop expansion. In addition to increased intensity, experiments will reach higher accuracy, and these improvements are being matched by developments in theory such as in approximation frameworks, the description of finite-size effects, and the range of physical phenomena analysed. Topics on which there has been substantial progress include: radiation reaction, spin and polarisation, nonlinear quantum vacuum effects and connections to other fields including physics beyond the Standard Model.

“…They first studied laser field effects on relativistic atomic physics scattering processes [2,3]. Then, they studied some laser-assisted weak decay processes [4,5]. Due to the significant advancements achieved by laser technology lately [6], it becomes possible to encourage the laser-assisted production of heavy elementary particles such as neutral higgs pair production [7], charged higgs pair production [8] and Higgsstrahlung production [9].…”

In this study, we have investigated the production of a charged Higgs boson in assiciation with a charged weak W -boson (H ± W ∓ ) at tree level via e + e − annihilation in the presence of a laser field with circular polarization. At first step and by using analytical techniques, we have derived the expression of the differential cross section involving both Z and γ diagrams. Next, we have shown that the cross section of this process inside the laser field is proportional to the form factor F HW V , and it depends on the mass of the charged Higgs boson and the energy of the center of mass. Then, we have analyzed the dependence of the total laser-assisted cross section on the number of photons exchanged for two different cases of form factor. Finally, we have found that the maximum number of photons that can be transferred depends only on the laser parameters.

“…Nowadays, such high-power laser systems motivate researchers to study fundamental processes in electroweak and quantum electrodynamics in the presence of a strong electromagnetic field realistic in experiments. Some typical processes in high energy are laser-assisted scattering [12][13][14] and decay processes [15][16][17]. In [18], we have discussed the effect of a strong electromagnetic field with a circular polarization on the cross section of the charged Higgs pair production in the Inert Higgs Doublet Model (IHDM).…”

In this paper, we have theoretically studied the neutral Higgs pair production in Two Higgs Doublet Model (THDM) in the presence of a circularly polarized laser field. The laser-assisted differential partial cross section is derived in the centre of mass frame at the leading order including Z diagram. The total cross section is computed numerically by integrating the differential cross section over the solid angle dΩ. Two benchmark points are discussed for the THDM parameters. In the first step, we have analyzed the total cross section of e + e − → h 0 A 0 by considering H 0 as the standard model-like Higgs boson. Then, the process e + e − → H 0 A 0 is studied by taking h 0 as the Higgs boson of the standard model. For both benchmark points, the laser-assisted total cross section of the studied processes depends on the produced neutral Higgs masses, the centre of mass energy and the laser field parameters. In addition, the maximum cross section occurs at high centre of mass energy for the process e + e − → H 0 A 0 as compared to that of e + e − → h 0 A 0 .
