摘要:Accurately calculating the mass of flavor-singlet meson states from numerical lattice simulations
is an important milestone for lattice QCD. Careful measurement of the full pseudoscalar flavorsinglet
propagator is also a crucial step in understanding the dynamics of the fermion sea on
the lattice, in particular for potentially non-trivial formulations such as with 2+1-flavor staggered
fermions. We briefly describe details of a dynamical QCD calculation using improved staggered
fermions, with 30,000 trajectories, that was run for our studies of flavour singlet mesons.
