The G0 experiment will measure the contribution of the strange sea quarks to the charge and magnetic distributions of the proton by measuring parity-violating asymmetries in elastic electron-nucleon scattering. The experiment is being performed in Hall C using a polarized electron beam and a dedicated experimental setup. To achieve an uncertainty of 5% on the measured asymmetries, which are of order 10-6, systematic effects that can induce false asymmetries must be controlled. One such effect is helicity-correlated changes in beam parameters, such as charge, beam position, beam angle, and beam energy. This seminar will present an overview of the G0 experiment, the major goals of the experiment, experimental techniques of parity-violating electron scattering, and experimental methods to minimize helicity-correlated effects.
