Abstract
We present the spectrum of ground state heavy-light mesons. Our analysis is provided by a symmetry preserving Schwinger-Dyson Bethe-Salpeter Equation (SDBSE) approach of a vector-vector contact interaction model. This model offers a simple-to-implement alternative to perform exploratory studies of QCD. Despite the simplicity of this model, our results for D are in agreement within 9%, and for B within 2% when we compare them with experimental data.
