Abstract

We present new lattice investigations of finite-temperature transitions for SU(3) gauge theory with Nf=8 light flavors. Using nHYP-smeared staggered fermions we are able to explore renormalized couplings $g^{2} ≲ 20$ on lattice volumes as large as $4 8^{3} \times 24$ . Finite-temperature transitions at non-zero fermion mass do not persist in the chiral limit, instead running into a strongly coupled lattice phase as the mass decreases. That is, finite-temperature studies with this lattice action require even larger $N_{T} > 24$ to directly confirm spontaneous chiral symmetry breaking.
