摘要：Many results from lattice QCD of broad importance to particle and nuclear physics are obtained
with 2+1 flavors of staggered sea quarks. In the continuum limit, staggered fermions yield four
species, called tastes. To reduce the number of tastes to one (per flavor), the simulation employs
the fourth root of the four-taste staggered fermion determinant. This talk surveys evidence in
favor of this procedure, refutes recent criticisms, and reviews recent algorithmic and technical
improvements. Physics results are covered in other plenary talks.
