  ABSTRACT: We have measured the parity-violating electroweak asymmetry in the elastic scattering of polarized electrons from the proton. The result is A=−15.05±0.98(stat)±0.56(syst) ppm at the kinematic point 〈θlab〉=12.3° and 〈Q2〉=0.477 (GeV/c)2. Both errors are a factor of two smaller than those of the result reported previously. The value for the strange form factor extracted from the data is , where the first error is experimental and the second arises from the uncertainties in electromagnetic form factors. This measurement is the first fixed-target parity violation experiment that used either a “strained” GaAs photocathode to produce highly polarized electrons or a Compton polarimeter to continuously monitor the electron beam polarization.

  ABSTRACT: A new Compton polarimeter is built on the CEBAF Hall A electron beam line. Performances of 10% resolution and 1% calibration are required for the photon calorimeter of this polarimeter. This calorimeter is built with lead tungstate scintillators coming from the CMS electromagnetic calorimeter R&D. Beam tests of this detector have been made using the tagged photon beam line at MAMI, Mainz, and a resolution of has been measured.
