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.

Derivation of Meson Masses in SU(3) and SU(4) Extended Linear Sigma Model at Finite Temperature

Particles
The present study focused on the mesonic potential contributions to the Lagrangian of the extended linear sigma model (eLSM) for scalar and pseudoscalar meson fields across various quark flavors.
