“…(26) of [1]. The corrections that we made allowed us to study other processes that were published in Physical Review A., namely an first article concerning the relativistic electronic dressing in laser assisted electron-hydrogen elastic collisions [10], another concerning the process of Mott scattering in an elliptically polarized laser field [11] as well as a third work dealing with the process of Mott scattering of polarized electrons in a strong laser field [12]. For the difficult process of ionization of atomic hydrogen by electron impact, we published an article concerning the importance of the relativistic electronic dressing in laser-assisted ionization of atomic hydrogen by electron impact [13].…”

Mott scattering in strong laser fields revisited

In this work, we review and correct the first Born differential cross section for the process of Mott scattering of a Dirac-Volkov electron, namely, the expression (26) derived by Szymanowski et al [Physical Review A 56, 3846 (1997)]. In particular, we disagree with the expression of dσ dΩ they obtained and we give the exact coefficients multiplying the various Bessel functions appearing in the scattering differential cross section. Comparison of our numerical calculations with those of Szymanowski et al. shows qualitative and quantitative differences when the incoming total electron energy and the electric field strength are increased particularly in the direction of the laser propagation. Such corrections are very important since the relativistic electronic dressing of any Dirac-Volkov charged particle gives rise to these coefficients that multiply the various Bessel functions and the relativistic study of other processes (such as excitation, ionisation, etc....) depends strongly of the correctness and reliability of the calculations for this process of Mott Scattering in presence of a laser field. Our work has been accepted [Y. Attaourti, B. Manaut, Physical Review A 68, 067401 (2003)] but only as a comment. In this paper, we give the full details of the calculations as well as the clear explanation of the large discrepancies that their results could cause when working in the ultra relativistic regime and using a very strong laser field corresponding to an electric field ε = 5.89 in atomic units.

“…Studies in the field of laser-matter interactions usually deal with non-relativistic [4] and relativistic atomic physics [5,6]. For example, in the study of Mott scattering of an electron by a charged nucleus in the presence of an electromagnetic field with a given polarization (linear, circular or elliptical), they showed that the intensity of the electric field, the kinetics of the incident electron and the collision geometry influence the behavior of the cross section [7]. Today, the technological progress gives us the opportunity to introduce an external electromagnetic field in high energy physics interactions.…”

“…Today, the technological progress gives us the opportunity to introduce an external electromagnetic field in high energy physics interactions. Indeed, several studies have been made to study the impact of the laser field on the decay width [8][9][10][11][12] and on the effective cross section [7,[13][14][15] by introducing the phenomenon of emission and/or absorption of photons [16]. For instance, in the study of nuclear decay β, there have been debates on the possibility of having significant effects by the presence of a strong laser pulse [8][9][10][11].…”

In this study, we have investigated the two-body hadronic decay of the charged kaon, K + → π + + π 0 , in the presence of a laser field with circular polarization. We have derived, by analytical techniques, the laser-assisted decay width and the branching ratio of the charged kaon decay via the two-body hadronic channel. We have also taken into consideration the impressive results obtained for the laser-assisted charged kaon decay via the leptonic mode in order to understand more clearly the effect of the laser field on the quantities related to the charged kaon decay such as the decay width, the branching ratio and lifetime. A precise comparison of the ratios of hadronic to muonic decay in the presence of the laser field is made to show that the hadronic mode becomes slightly more important by increasing the laser field intensity.

“…The MPP of potential scattering in the relativistic regime has been investigated in [3]. Nonlinear Compton scattering induced by a linearly polarized laser field with high-velocity electrons has been studied by [4], while a subsequent investigation is the Coulomb scattering-the so-called Mott scattering in the presence of a linearly and elliptically polarized laser field [5][6][7][8][9]. Moreover, many authors have been enthusiastically investigating some other interesting MPP processes, such as particle decay in the presence of laser fields within weak interactions [10][11][12], the laser-assisted bremsstrahlung [13,14], and pair production [15].…”

“…In view of the prominent influence of applied laser field on the collision process just as depicted in [3][4][5][6][7][8][9][10][11][12][13][14][15], in this paper * brite@mail.ustc.edu.cn we concentrate on the laser-assisted muon-neutrino-electron elastic scattering process ν μ + e − → ν μ + e − . The electrons immersed in laser fields will be dressed as Dirac-Volkov states [17] in the initial and final channels, which would lead to considerable multiphoton processes.…”

Multiphoton processes in laser-assisted scattering of a muon neutrino by an electron

We study the elastic scattering of a muon neutrino by an electron in the presence of a linearly polarized laser field in the frame of the standard model, and multiphoton processes are observed. The distributions of a multiphoton energy transfer (MPET) spectrum are greatly affected even by the laser fields in a moderate intensity range, while the total differential cross section can be largely changed by several orders of magnitude only in extreme strong laser fields with ultrarelativistic electrons. The method of stationary phase approximation is used for analyzing and elucidating the phenomena of cutoff, oscillation, and shift found in a MPET spectrum. We also analyze the reason giving rise to "dark windows" and geometric asymmetry initially noted in the potential scattering. By comparing the results we reach the conclusion that these effects are closely related to the order and arguments of generalized Bessel functions.
