Available in PDF, EPUB and Kindle. Book excerpt: We present a calculation of the light-hadron spectrum in full QCD using three-flavor Asqtad sea quarks and domain wall valence quarks. Calculations of meson masses, meson and baryon masses are performed on a lattice of spatial size $L\simeq 2.5$~fm, and a lattice spacing of $a \simeq 0.124$~fm, for pion masses as light as $m_\pi \sim 300$~MeV. Extrapolation of baryon masses to the physical pion mass is studied using continuum and mixed action heavy baryon chiral perturbation theory for two and three flavors. The success and limitations of chiral perturbation theory with these extrapolations is discussed.
