Baryon masses with atad2 staggered quarks

Presenter: Doug Toussaint — University of Arizona

the MILC collaboration: C. Bernard, C. DeTar, Steven Gottlieb, U.M. Heller, J.E. Hetrick, L. Levkova, J. Osborn, D. Renner, R. Sugar, D. Toussaint

The MILC collaboration's simulations with improved staggered quarks are being extended with runs at a lattice spacing of 0.06 fm. We give a brief introduction to these new simulations and the determination of the lattice spacing. Then we combine these new runs with older results to study the masses of the nucleon and the Ω in the continuum and chiral limits.
