A bstract We explore the topological susceptibility at finite quark chemical potential and zero
temperature in two-color QCD (QC 2 D) with two flavors. Through the Ward-Takahashi …

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

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 …

We analyze the restoration pattern of the members of the scalar and pseudoscalar meson
nonets under chiral O (4) and U (1) A symmetries. For that purpose, we exploit QCD Ward …

We find that a big gap between indicators for the breaking strengths of the global chiral SU
(2) and U (1) axial symmetries in the QCD of the standard model (SM) can be interpreted as …

We present and analyze a new set of Ward Identities which shed light on the distinction
between different patterns of chiral symmetry restoration in QCD, namely O (4) vs O (4)× U …

We show that the σ/f 0 (500) state with finite-temperature T corrections to its spectral
properties included plays an essential role for the description of the scalar susceptibility χ S …

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 …
