The $\eta - \eta'$ Mixing Angle Revisited

, 1997
The value of the $\eta - \eta'$ mixing angle $\theta_P$ is phenomenologically deduced from a rather exhaustive and up-to-date analysis of data including strong decays of tensor and higher-spin mesons, electromagnetic decays of vector and pseudoscalar ...

Chiral Symmetry restoration from the hadronic regime

EPJ Web of Conferences, 2017
We discuss recent advances on QCD chiral symmetry restoration at finite temperature, within the theoretical framework of Effective Theories. U(3) Ward Identities are derived between pseudoscalar susceptibilities and quark condensates, allowing to explain

Quarkonia and heavy-light mesons in a covariant quark model

EPJ Web of Conferences, 2016
Preliminary calculations using the Covariant Spectator Theory (CST) employed a scalar linear confining interaction and an additional constant vector potential to compute the mesonic mass spectra.
