The spinorial character of the gentilionic baryon states

Creators

Description

It is shown that the wavefunction, in an internal colour space of three quarks taken as gentileons, has a bi-spinorial character. In this context, the formalism differs drastically from parastatistics and fermionic theories of quarks. As a direct consequence of the spinorial character the SU(3)colour representation can naturally be incorporated into the S3 gentilionic symmetry and a selection rule for quark confinement is deduced. Comparing the results with Dirac's bi-spinorial formulation and with Prentki-d'Espagnat theory, striking resemblances are found. (Author)

Abstract (Portuguese)

Mostra-se que a funcao de onda, em um espaco de cores interno, para tres quarks considerados como gentileons, tem um carater bi-espinorial. Neste contexto, o formalismo difere drasticamente das teorias para estatistica e fermionica dos quarks. Como consequencia direta do carater espinorial a representacao SU(3)cor pode naturalmente ser incorporada na Simetria gentilionica S(3) e uma regra de selecao para confinamento de quarks ser deduzida. Comparando-se os resultados com a formulacao bi-espinorial de Dirac e com a teoria de Prentki-d'Espagnat, surpreendentes semelhancas sao encontradas. (S.D.)
