“…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).
