Description
In this talk, I will report on recent results concerning chiral and U(1)_A restoration, both from an analysis based on Ward identities, which are formally derived from QCD, and from effective field theories, which are provided by U(3) chiral perturbation theory.
These results lead to relevant conclusions about the behavior of chiral partners (in terms of susceptibilities) in the limit of exact restoration and explain the current tension between Nf=2 and Nf=2+1 lattice simulations regarding U(1)_A restoration.
