Eight light flavors on large lattice volumes

Understand

I present first results from large-scale lattice investigations of SU(3) gauge theory with eight light flavors in the fundamental representation.

• Using leadership computing resources at Argonne, we are generating gauge configurations with lattice volumes up to $64^3\times128$ at relatively strong coupling, in an attempt to access the chiral regime.
• We use nHYP-improved staggered fermions, carefully monitoring finite-volume effects and other systematics.
• Here I focus on analyses of the light hadron spectrum and chiral condensate, measured on lattice volumes up to $48^3\times96$ with fermion masses as light as m=0.004 in lattice units.
