"Electromagnetic Form Factors of a Nucleon in Full Lattice QCD"

Presented by Sergey Syritsyn, Massachusetts Institute of Tehnology

Thursday, October 8, 2009, 12:30 pm — Rm 2-160; Bldg. 510

I will present a recent high-statistics calculation of nucleon electromagnetic form factors using lattice QCD with 2+1 flavors of dynamical domain wall quarks. This is the first calculation with (almost) chirally symmetric both sea and valence quark actions at pion masses down to m_\pi=300MeV and at lattice spacing as small as a=0.084fm. Using specially tuned techniques to suppress gauge noise and excited state contaminations, we determine the nucleon form factors with a remarkable precision. I will also present the exrapolation of our results using two-flavor chiral perturbation theory and comparison to experiment.
