TL;DR: In this article, the current status of the MILC collaboration's calculations of the light pseudoscalar meson sector is presented, and fits to the data using chiral forms from SU(3) chiral perturbation theory, including all staggered taste violations at NLO and the continuum NNLO chiral logarithms.

TL;DR: In this paper, the MILC collaboration's analysis of the light pseudoscalar meson sector was presented, which includes data from new ensembles with smaller lattice spacings, smaller light quark masses and lighter-than-physical strange quark mass.

TL;DR: In this paper, the MILC collaboration's analysis of the light pseudoscalar meson sector with SU(3) chiral fits was presented, which includes data from new ensembles with smaller lattice spacing, smaller light quark masses and lighter than physical strange quark mass.

TL;DR: In the light pseudoscalar sector, the authors studied rooted staggered chiral perturbation theory in the two-flavor case and showed that the SU(2) and SU(3) chiral theories emerge from the SU (3) theory, as expected, in the limit where the strange quark mass is large compared to the light quark masses.

TL;DR: In the light pseudoscalar sector, this article studied rooted staggered chiral perturbation theory in the two-flavor case and derived the pion mass and decay constant through NLO for a partially-quenched theory.
