Meson decay in a correctedP03model

Abstract: Extensively applied to both light and heavy meson decay and standing as one of the most successful strong decay models is the 3 P0 model, in which qq pair production is the dominant mechanism. The pair production can be obtained from the non-relativistic limit of a microscopic interaction Hamiltonian involving Dirac quark fields. The evaluation of the decay amplitude can be performed by a diagrammatic technique for drawing quark lines. In this paper we use an alternative approach which consists in a mapping te… Show more

“…As propriedades destes compósitos ganharam tanto destaque na literatura que estão impulsionando o aprimoramento do processo de obtenção, em grande escala, destas cargas. [8][9][10][11] Neste contexto, o presente trabalho teve como objetivos a obtenção de nanopartículas de celulose e adicioná-las como reforço no PLA. Foi avaliada a influência da carga no comportamento térmico, morfológico e reológico do polímero.…”

“…Geralmente, essas nanopartículas são formadas pela estrutura da celulose I. [1,8] A respeito da nomenclatura das nanopartículas de celulose não há uma padronização e, por isso, há um uso inconsistente de termos na literatura para descrever um dado conjunto de partículas de celulose. Existem apenas tendências atuais em terminologia, utilizadas de acordo com o tamanho das partículas, porcentagem de cristalinidade, morfologia e propriedades das mesmas.…”
