Abstract

We report a new determination of the strange quark contribution to the proton's magnetic form factor at a four-momentum transfer Q²=0.1 (GeV/c)² from parity-violating e-p elastic scattering. The result uses a revised analysis of data from the SAMPLE experiment which was carried out at the MIT-Bates Laboratory. The data are combined with a calculation of the proton's axial form factor G^e_A to determine the strange form factor G^s_M(Q²=0.1)=0.37±0. 20±0.26±0.07. The extrapolation of G^s_M to its Q²=0 limit and comparison with calculations is also discussed.
