The parity-violating asymmetry including QED corrections in high-energy electron-nucleus collisions
Xavier Roca-Maza, D. H. Jakubassa-Amundsen
The parity-violating asymmetry, accounting for the vector and axial-vector vertex plus self-energy correction as well as for vacuum polarization, is calculated nonperturbatively by…
Dispersion effects in elastic electron scattering from Pb
D. H. Jakubassa-Amundsen, X. Roca-Maza
Dispersion corrections to elastic electron scattering from Pb at energies up to 150 MeV are estimated within the second-order Born approximation. All strong transient nucle…
The Electron-Gamma Coincidence Setup DAGOBERT
B. Hesbacher, G. Steinhilber, J. Isaak +9
The QCLAM electron spectrometer at the S-DALINAC electron accelerator at Technische Universität Darmstadt has been extended by the DAGOBERT -detector array consisting of fast…
QED corrections to the parity-violating asymmetry in high-energy electron-nucleus collisions
Xavier Roca-Maza, D H. Jakubassa-Amundsen
The parity-violating asymmetry, including leading-order QED corrections to the Coulomb potential, is calculated non-perturbatively by solving the Dirac equation. At GeV collision e…
Simultaneous Extraction of the Weak Radius and the Weak Mixing Angle from Parity-Violating Electron Scattering on
Matteo Cadeddu, Nicola Cargioli, Jens Erler +4
We study the impact of nuclear structure uncertainties on a measurement of the weak charge of at the future MESA facility in Mainz. Information from a large varie…
