Description
Summary:(ProQuest: ... denotes formulae and/or non-USASCII text omitted)A revised global fit of electroweak ep and vp elastic scattering data has been performed, with the goal of determining the strange quark contribution to the vector and axial-vector form factors of the nucleon in the momentum-transfer range 0 < Q super(2) < 1 GeV super(2). The two vector (electric and magnetic) form factors ... and ... are strongly constrained by ep elastic scattering data, while the major source of information on the axial-vector form factor ... is vp scattering data. Combining the two kinds of data into a single global fit makes possible additional precision in the determination of these form factors, and provides a unique way to determine the strange quark contribution to the nucleon spin, Delta S, independently of leptonic deep-inelastic scattering. The fit makes use of data from the BNL-E734, SAMPLE, HAPPEx, GO, and PVA4 experiments; we will also compare the result of the fit with recent data from MiniBooNE, and anticipate how this fit can be improved when new data from MicroBooNE become available.
