From the analysis of the results we estimate the masses of mesons with hottom not yet found experimentally. We discuss the behaviour of the confinement potential under Lorentz transformation and calculate the spin-dependent corrections. We also calculate the electromagnetic decay rates and the leptonic and hadronic decay widths for some mesons. © 1985 Società Italiana di Fisica.161-168eng12.85Composite models of particlesArtigo10.1007/BF02746973Acesso restrito2-s2.0-512491710715811700083195480
