“…The model was originally implemented to compute the spectrum, decay constant and electromagnetic form factor of pion, rho mesons and their diquark partners [11,13]. Successive works expanded this model to study unflavored heavy systems [16,17], heavy-light systems [18,19] and baryons [14,[20][21][22]. In these studies, there is a general consensus on obtaining that the mass spectrum of mesons and baryons is in a good agreement with experimental data.…”

A collection of different studies about bound states of hadrons composed of charm quarks is presented. These studies used a symmetry preserving vector-vector contact interaction model within the framework of Schwinger-Dyson and Bethe-Salpeter equations. Despite its limitations, the contact interaction model offers a simple-to-implement alternative to perform exploratory studies of QCD, obtaining an spectrum of charmed hadrons in agreement within 2% when they are compared with experimental data. In particular, the spectrum of charm and beauty mesons is presented.
