We compute a full set of the first order QED corrections to the parity-violating observables in polarized Moller scattering. We employ a covariant method of removing infrared divergences, computing corrections without introducing any…

Experiment E158 at SLAC can measure an azimuthal asymmetry in single-spin, transversely polarized Moller scattering, e^{-\uparrow} e^- -> e^- e^-, which arises from a QED rescattering phase. We recompute the leading-order (one-loop)…

The SLAC PES, developed in the early 1990s for the SLC, has been in continuous use since 1992, during which time it has undergone numerous upgrades. The upgrades include improved cathodes with their matching laser systems, modified…

The precision physics program of the ILC requires precise knowledge of the state of beam polarisation. In fact the Compton polarimeters intended for the ILC will have to measure the polarisation with error a factor of 2 smaller than the…

Parity-violating asymmetries in polarized electron scattering have been interpreted as the asymmetries between opposite helicities of incoming fermion based on the approximation of the spin polarization operator. Here exact calculations of…

Full exploitation of the physics potential of a future International Linear Collider will require the use of polarized electron and positron beams. Experiment E166 at the Stanford Linear Accelerator Center (SLAC) has demonstrated a scheme…

For the 1994/95 run of the SLD experiment at SLAC, a Compton polarimeter measured the luminosity-weighted electron beam polarization to be (77.2 +- 0.5)%. This excellent accuracy is achieved by measuring the rate asymmetry of…
