A review of the present understanding of η′ and η meson physics and these mesons as a
probe of gluon dynamics in low-energy QCD is presented. Recent highlights include the …

Renormalization group flows of the SU (N f)× SU (N f) symmetric Ginzburg-Landau potential
are calculated for a general number of flavors, N f. Our approach does not rely on the ε …

We introduce novel relations between the derivatives [∂ n ρ (λ, ml)/∂ mln] of the Dirac
eigenvalue spectrum [ρ (λ, ml)] with respect to the light sea quark mass (ml) and the (n+ 1) …

We present lattice QCD results for mesonic screening masses in the temperature range 140
MeV≲ T≲ 2500 MeV. Our calculations were carried out using (2+ 1) flavors of the highly …

We investigate the order of the QCD chiral transition in the limit of vanishing bare up/down
quark masses and variations of the bare strange-quark mass 0≤ ms≤∞. In this limit and …

The nonsinglet part of the chiral symmetry in quantum chromodynamics (QCD) with two light
flavors is known to be restored through a crossover transition at a pseudocritical …

Based on a complete set of J= 0 and J= 1 spatial isovector correlation functions calculated
with NF= 2 domain wall fermions we identify an intermediate temperature regime of T∼ 220 …

We investigate the axial U (1) anomaly of two-flavor QCD at temperatures 190–330 MeV. In
order to preserve precise chiral symmetry on the lattice, we employ the Möbius domain-wall …

I derive constraints on the Dirac spectrum in the chirally symmetric phase of a gauge theory
with two massless fermion flavors. Using only general properties of correlation functions of …

We calculate the eigenmodes of the highly improved staggered quark matrix near the chiral
crossover transition in QCD with 2+ 1 flavors with the aim to gain more insights into its …
