Abstract

The A4 collaboration at the MAMI accelerator at Mainz investigates the contribution of strange quarks to the form factors of the nucleon by measuring the parity violating asymmetry A PV in the cross section of elastic scattering of longitudinally polarized electrons off hydrogen and deuterium. Recently, measurements at backward angles at a four momentum transfer of Q 2 = 0.22 GeV2 were completed. Together with previous results at forward angles at the same momentum transfer, the strange electric and magnetic form factors \(G_E^s\) and \(G_M^s\) can be disentangled.
