It introduces a nonlocal SU(2) PNJL model with wave function renormalization and vector interactions, providing new insights into meson properties and phase diagram features.

## Key findings

- Meson masses, widths, and decay constants at finite temperature
- Phase diagram with deconfinement and chiral restoration transitions
- Behavior of mesons under varying temperature and density

## Abstract

We study the features of a SU(2) Polyakov-Nambu-Jona-Lasinio model that includes wave function renormalization and nonlocal vector interactions. Within this framework we analyze, among other properties, the masses, width and decay constants of light vector and axial-vector mesons at finite temperature. Then we obtain the corresponding phase diagram in a finite density scenario, after characterizing the deconfinement and chiral restoration transitions.
