Description
In this talk, I present our recent results on the hadron spectra in QCD. We show that hadrons in QCD follow a spectrum determined by string dynamics characterized by a universal Hagedorn temperature linked to the string tension. This behavior was recently established for light hadrons and glueballs [1, 2]. We also demonstrate that the same dynamics describes the heavy-flavor sector [3]. The resulting spectra reproduce lattice QCD thermodynamics of light and charmed hadrons and the observed spectra of hadrons across quark flavors without additional parameters. These results reflect the universal confining dynamics of QCD through the string tension.
