A Study of Small Angle Radiative Bhabha Scattering and Measurement of the Luminosity at SLD
2004
Abstract
Small angle Bhabha scattering (e{sup +}e{sup -} {yields} e{sup +}e{sup -}) is used to measure the luminosity for the 1993 run of the SLD experiment. SLD operates at the Stanford Linear Collider at Stanford Linear Accelerator Center where electrons and positrons are collided at center of mass energy on the Z{sup 0} resonance. A silicon tungsten luminosity monitor is used to record the Bhabha events and a description of this device and its performance is presented. The luminosity is measured using two different methods to correct for small displacements in the luminosity monitor and the results are given. Measurement of the integrated luminosity is essential for the determination of the cross section for all final states in the experiment.
