Strange quark contribution to nucleon form factors

Presenter: Ronald Babich — Boston University

We discuss methods for the calculation of disconnected diagrams and their application to various form factors of the nucleon. In particular, we present preliminary results for the strange contribution to the scalar and axial form factors, calculated with Nf=2 dynamical flavors of Wilson fermions on an anisotropic lattice.
