"Chiral extrapolation of nucleon magnetic form factors"

Ping Wang , JLAB
[Host: Simonetta Liuti]
The extrapolation of nucleon magnetic form factors calculated within lattice QCD is investigated within a framework based upon heavy baryon chiral effective-field theory. All one-loop graphs are considered at arbitrary momentum transfer and all octet and decuplet baryons are included in the intermediate states. Finite range regularisation is applied to improve the convergence in the quark-mass expansion. The resulting values of the form factors at the physical pion mass are in good agreement with the experimental data.
