摘要：The MILC collaboration’s simulations with improved staggered quarks are being extended with
runs at a lattice spacing of 0.06 fm with quark masses down to one tenth the strange quark mass.
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
W− in the continuum and chiral limits.
