“…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). The laser-assisted neutral Higgs pair production in IHDM is discussed in [19], and we have found that the electromagnetic field decreases the cross section. In this respect, we have investigated the same process (e + e − → H 0 A 0 ) in THDM in order to analyze the effect of the circularly polarized laser field on its cross section.…”

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 .

“…In view of the new developments in laser technology, high intensity and short duration laser pulses are generated nowadays in the laboratory [1][2][3]. This has greatly inspired researchers to study various ultrafast processes in the presence of strong laser fields, such as atomic processes [4][5][6][7][8][9][10] and those that occur in the frameworks of quantum electrodynamics (QED) [11][12][13][14][15] and electroweak theory [16][17][18][19][20][21], as well as recently the processes of Higgs boson production beyond the Standard Model [22][23][24]. New experimental perspectives for the study of these processes in the presence of laser field are proposed by future high field laboratories, such as the Extreme Light Infrastructure (ELI) [25] and the Exawatt Center for Extreme Light Studies (XCELS) [26].…”

This work aims to study theoretically the electron-proton scattering for initially spin-polarized electrons in the presence of a circularly polarized electromagnetic field. Using the first Born approximation and the Dirac-Volkov states for dressed electrons, we derive an analytic expression for the differential cross-section with the help of the spin-helicity formalism. Meanwhile, a wellknown concept of spin-flip and spin non-flip differential cross sections is applied. The influence of the electromagnetic field on the degree of polarization of the scattered electron is investigated, and the effect of electron spin polarization is examined. We found that the initial spin of the electron can be affected depending on its kinetic energy during the scattering process. This work is a continuation of a recent paper in which we studied the unpolarized electron-proton scattering in the presence of a laser field (Dahiri, et al., Laser Phys. Lett. 18 (2021) 096001).

“…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]. This is being achieved by relying on high-intensity laser sources which provide the incident beam e + e − with high kinetic energies.…”

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.
