Hadron phenomenology

The subjects here related constitute a summary of some recent collaborations of which details can be found in the references correspondent to each one. One exception is made to the last part (Glueballs) where a new collaboration is going on. These constitute therefore our recent interest in Hadron Phenomenology, looking into models which have been used for explanation o some physical phenomena found in the last years of particle physics. Production processes of heavy flavor bound states, an indirect manifestation of the possible existence a Diquarks, the problems posed by the spin-parity Jp = 1 + mesons and finally evidence for the observation of Glueballs are discussed.
