Nucleon electromagnetic form factors with Wilson fermions

Presenter: Wolfram Schroers — NIC - DESY Zeuthen

Wolfram Schroers [on behalf of the QCDSF collaboration]

The nucleon's electromagnetic form factors continue to be of major interest for experimentalists and phenomenologists alike. They provide important insights into the structure of nuclear matter. For a range of interesting energies they can be calculated on the lattice. The limiting factor for these observables remains to be the value of the pion mass. We present the latest results of the QCDSF collaboration using gauge configurations with two dynamical, non-perturbatively improved Wilson fermions at pion masses as low as 300 MeV.
