| Title | Probing the standard model and nucleon sturcture via partiy violating electron scattering | ||||
| Abstract | Parity-violating electron scattering has developed over the last 25 years into a tool to study both the structure of electroweak interactions and the structure of nucleons. This thesis reports work on two parity-violation experiments, the Hall A Proton Parity Experiment (HAPPEX) and SLAC E-158. HAPPEX (Jefferson Laboratory, 1998-1999) measured the parity-violating asymmetry in elastic e-p scattering at Q 2 = 0.477 GeV 2 . This asymmetry is sensitive to the proton's strange elastic form factors. An asymmetry of A LR = -15.05 ± 0.98(stat) ± 0.56(syst) ppm was measured. This asymmetry measurement allowed HAPPEX to set new constraints on the strange elastic form factors of the proton: [Special characters omitted.] where G Es and G Ms are the strange electric and magnetic form factors of the proton, respectively. The first error is the quadrature sum of the experimental errors and the second error is due to uncertainty in electromagnetic form factors. This result is consistent with the | ||||
