“…q indicates the fourmomentum of the off-shell V (V = Z or γ). After introducing a short description of the procedure used to analyze the effects of laser field on the process 1, we substitute the expressions of wave functions (equations ( 6) and ( 9)) and Feynman propagators (equations ( 11) and ( 12)) into the equation (10). Thus, we obtain:…”

“…Detailed reports on laser-assisted elementary particles' production via electron-positron annihilation can be found in the papers [10,11]. In addition, the laser-assisted electron-positron annihilation allows the observation of a variety of new phenomena related to high energy physics such as the standard model of particle physics and beyond.…”

In the framework of Higgs triplet model (HTM), we study the pair production process of doubly charged Higgs bosons via e + e − annihilation in the presence of a laser field with circular polarization . We begin our work by presenting the theoretical calculation of the differential cross section in the centre of mass frame including both Z and γ diagrams. Then, from the numerical analysis of the production cross section's dependence on the laser field parameters, we have shown that the laser-assisted total cross section decreases as far as the electromagnetic field intensity enhances or by decreasing its frequency. Finally, we analyze the variation of the total cross section versus the mass of the doubly charged Higgs boson by fixing the laser field parameters and the centre of mass energy, and we have found that the order of magnitude of the cross section decreases as long as M H ±± increases.

“…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).

“…In ref [11], it is found that the laser field has a great impact on the pion's behavior and its properties such as the decay rate and the particle's lifetime. Moreover, it is shown that the laser field decreases the total cross section of heavy elementary particles' production (see [9,10] for more details).…”

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.
