Abstract

In this work, the conversion of linear polarization of a laser beam to circular one through its forward scattering by a TeV order charged lepton beam in the presence of Lorentz violation correction is explored. We calculate the ratio of circular polarization to linear one (Faraday Conversion phase ΔϕFC\Delta\phi_{\rm{FC}}) of the laser beam interacting with either electron or the muon beam in the framework of the quantum Boltzmann equation. Regarding the experimentally available sensitivity to the Faraday conversion ΔϕFC103102\Delta\phi_{\rm{FC}}\simeq 10^{-3}-10^{-2}, we show that the scattering of a linearly polarized laser beam with energy k00.1k_0\sim 0.1 eV and an electron/muon beam with flux ϵˉe,μ1010/1012\bar{\epsilon}_{e,\mu}\sim 10^{10}/10^{12} TeV cm2^{-2} s1^{-1} places an upper bound on the combination of lepton sector Lorentz violation coefficients cμνc_{\mu\nu} components (cTT+1.4 c(TZ)+0.25(cXX+cYY+2 cZZ))(c_{TT}+1.4~c_{(TZ)}+0.25(c_{XX}+c_{YY}+2~c_{ZZ})). The obtained bound on the combination for the electron beam is at the 4.35×10154.35\times 10^{-15} level and for the muon beam at the 3.9×10133.9\times 10^{-13} level. It should be mentioned that the laser and charged lepton beams considered here to reach the experimentally measurable ΔϕFC\Delta\phi_{\rm{FC}} are currently available or will be accessible in the near future. This study provides a valuable supplementary to other theoretical and experimental frameworks for measuring and constraining Lorentz violation coefficients.
