National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Radiative Corrections to the Azimuthal Asymmetry in Transversely Polarized Moller Scattering.

DE2004826750

Publication Date	2004
Personal Author	Dixon, L.; Schreiber, M.
Page Count	12
Abstract	Experiment E158 at SLAC can measure an azimuthal asymmetry in single-spin, transversely polarized Moeller scattering, e(sup -)(up-arrow)e(sup -) (yields) e(sup -)e(sup -), which arises from a QED rescattering phase. We recompute the leading-order (one-loop) asymmetry, con.rming previous results, and calculate the leading logarithmic QED corrections due to initial-state radiation from the beam and target electrons, and due to final-state radiation. The size of these radiative corrections is quite sensitive to experimental details, such as the acceptance in energy and in polar angle of the scattered electron. For E158, the corrections are modest, increasing the parts-per-million asymmetry by roughly 1%.
