Abstract

We have measured the parity violating asymmetry with polarized electrons scattered elastically from protons. The result is A = -15.05 ± 0.98( stat ) ± 0.56( syst ) ppm at the kinematic point [left angle bracket][straight theta] lab [right angle bracket] = 12.3° and [left angle bracket] Q 2 [right angle bracket] = 0.477( GeV/c ) 2 . The value for the linear combination of the strange form factors found using A is [Special characters omitted.] + 0.392[Special characters omitted.] = 0.025 ± 0.020 ± 0.014 where the first error is experimental and the second stems from the uncertainties in the electromagnetic form factors.
