QED Corrections for Polarized Elastic μe Scattering
نویسندگان
چکیده
We present a new study of polarized elastic muon-electron scattering. The Born cross-section is calculated for arbitrary polarization of muon and electron. The complete photonic O(α) radiative corrections are determined for the case of longitudinally polarized muons and electrons. All calculations are done by two methods: semianalytic, which allows an implementation of the experimental cuts used for the analysis of μe scattering data from the beam polarimeter of the SMC experiment at CERN and completely analytic, which is used for cross checks. The FORTRAN code μela realizes formulae of both approaches. We prove that certain experimental cuts lead to negligible radiative corrections in the muon beam polarization experiment. a Supported by the Heisenberg-Landau fund. b Supported by the INTAS-93-744.

For neutrino scattering from polarized electron, the weak interaction term in the cross section is significantly suppressed by the polarized term. The magnetic moment term does not receive any correction from the electron polarization. Hence, the study of the magnetic moment of neutrinos through scattering from the polarized electron leads to a stronger bound on the neutrino magnetic moment com...
متن کاملUniversal QED Corrections to Polarized Electron Scattering in Higher Orders
We derive QED radiators for the universal corrections to polarized electron scattering. To 5th order in the coupling constant the flavor non-singlet and singlet contributions are calculated. We derive the non-singlet and singlet exponentiation of the leading terms ∝ (α ln(x))k to all orders. Contribution to DIS 2002, April 2002, Cracow.

Deep inelastic scattering provides us with detailed information on the nucleon structure. In order to extract the parton distribution functions from DIS cross sections and to measure αs(M 2 Z) with high precision it is crucial to control the QED radiative corrections. The 1– and 2–loop leading–log QED corrections were derived in Ref. [1–3]. Complete 1-loop corrections for DIS were given in Refs...
متن کاملOn radiative corrections for unpolarized electron proton elastic scattering
A statistical analysis of the elastic unpolarized electron proton scattering data shows that, at large momentum transfer, the size and the ǫ dependence of the radiative corrections, as traditionally calculated and applied, may induce large correlations of the parameters of the Rosenbluth fit, which prevent a correct extraction of the electric proton form factor. Using the electron QED structure...

The explicit exact expressions of QED lowest-order radiative corrections to the two polarized identical fermion scattering are presented in covariant form. Polarization effects are treated in detail. The infrared divergence from the real photon emission is extracted by covariant approach. Some numerical results for Møller scattering are given.
