Masses of light and heavy mesons in a $U(4{)}_r\times U(4{)}_l$ linear sigma model

Abstract

We extend the three-flavor linear sigma model with (axial-)vector mesons to four flavors. We compute the masses of (pseudo)scalar and (axial-)vector mesons including open and hidden charmed mesons as well as weak decay constants. The results are in good agreement with experimental data.
