Title Laser and Electron Beam Technology for Parity Violating Electron Scattering Measurements
Abstract Parity violating electron scattering (PVES) is a precision tool used in a broad program of experiments which include studying the structure of protons and nuclei and searching for new Beyond the Standard Model (BSM) physics. In parity violation electron scattering experiments, a longitudinally polarized electron beam is incident on an unpolarized target. The sign of the longitudinal polarization is changed (making a parity transformation), and the fractional rate difference between right and left helicity states, dsR and dsL, is measured. An interference between the electromagnetic and weak amplitudes, M¿ and MZ respectively, gives rise to a parity violating asymmetry APV = sR-sL sR+sL , defined by the fractional rate difference between right and left helicity states. APV can be measured to extraordinarily high precision and is proportional to the ratio of the weak and electromagnetic amplitudes. This thesis highlights three such PVES experiments as well as a new polarized beam source
