Description

The spectrum of masses of light and heavy mesons is calculated, using a potential that shows confinement and asymptotic freedom for quark antiquark pairs. From the analysis of the results the masses of mesons with beauty not yet found experimentally are estimated. The behaviour of the confinement potential under Lorentz transformation is discussed and the spin dependent corrections is calculated. The electromagnetic decay rates and the leptonic and hadronic decay widths for some mesons are also calculated. (Author)

Abstract (Portuguese)

Calcula-se o espectro das massas dos mesons leves e pesados, usando um potencial que engloba confinamento e liberdade assintotica para os pares quark-antiquark. Da analise dos resultados obtidos estima-se as massas dos mesons com beleza ainda nao descobertos experimentalmente. Discute-se a natureza do potencial confinante sob transformacao de Lorentz, e calcula-se as correcoes dependentes de spin. Calcula-se tambem taxas de trasicoes eletromagneticas e larguras dos decaimentos leptonicos e hadronicos para alguns mesons. (Autor)
