Centre-of-mass corrections for the harmonic S+V potential model

Creators

Description

Center-of-Mass corrections to the mass spectrum and static properties of low-lying S-wave baryoins are discussed in the context of a relativistic, independent quark model, based on a Dirac equation, with equally mixed scalar and vector confining potential of harmomic type. A more stisfactory fitting of the parameters involved is obtained, as compared with previous treatments which CM corrections were neglected. (Author)

Abstract (Portuguese)

Discutem-se as correcoes de centro-de-massa ao espectro de massa e as propriedades dos estados mais baixos de onda S dos barions no contexto de um modelo de quark independente relativistico, baseado na equacao de Dirac, com pontenciais de confinamento escalar e vetorial igualmente misturados do tipo harmonico. Obtem-se um ajuste satisfatorio dos parametros envolvidos quando comparados com tratamentos anteriores, nos quais as correcoes de centro-de-massa foram desprezadas. (L.C.)
