We review recent results on the role of light quark states within the QCD phase diagram. In
particular, we will discuss how the combined use of theoretical techniques such as Effective …

A bstract We perform a complete calculation of the pion-kaon scattering amplitude in Chiral
Perturbation Theory at finite temperature, paying particular attention to the analytic structure …

A bstract We analyze the contribution of the η′(958) meson in the first two non-trivial
moments of the QCD topological charge distribution, namely, the topological susceptibility …

A bstract Recent lattice data on ππ-scattering phase shifts in the vector-isovector channel,
pseudoscalar meson masses and decay constants for strange-quark masses smaller or …

In this work we have studied the QCD phase structure and critical dynamics related to the 3-
d O (4) and Z (2) symmetry universality classes in the two-flavor quark-meson low energy …

We review recent advances in the understanding of the Quantum Chromodynamics (QCD)
transition and its nature, paying special attention to the analysis of chiral symmetry …

In this paper we study the η′ in N f= 2+ 1+ 1 lattice QCD simulations at finite temperature.
Results are obtained from the analysis of the gluonic defined topological charge density …

We use recently derived Ward identities and lattice data for the light-and strange-quark
condensates to reconstruct the scalar and pseudoscalar susceptibilities (χ _S^ κ χ S κ, χ _P …

The renormalized contribution of fermions to the curvature masses of vector and axial-vector
mesons is derived with two different methods at leading order in the loop expansion applied …

Within the framework of the U (3) chiral perturbation theory, we revisit the masses, decay
constants, and the mixing parameters of the light pseudoscalar mesons π, K, η, and η′. The …
