On the stability of Quantum Hadro-Dynamics

Abstract

We explore the possible occurrence of $\sigma$-$\omega$ condensation in the Quantum Hadro-Dynamics (QHD), namely the Serot and Walecka model, finding that at the mean field level it corresponds to a critical value of the coupling constant $g_{\sigma }=8.828$ and density $k_F=207.2$ MeV/c, significantly below the standard value of QHD.
