Radial effects in the symmetric quark model

Радиальные эффекты в смметричной кварковой модели

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

Effects of the radial wave function are studied for the nonstrange baryons in the symmetric quark model. Rotational energy levels are calculated and are found to be in agreement with the energy levels in the observed baryonic mass spectra. Relativistic perturbative effects which vanish in the large-quark-mass limit are also calculated. The lower bound on the quark mass is found to be approximately 1.5 GeV.

Riassunto

Si studiano gli effetti della funzione d'onda radiale per barioni non strani nel modello. a quark simmetrico. Si calcolano i livelli d'energia rotazionali e si trova che essi concordano con i livelli d'energia negli spettri delle masse barioniche osservati. Si calcolano anche effetti perturbative relativistici che tendono a zero nel limite della grande massa dei quark. Si trova che il limite inferiore della massa dei quark è circa 1.5 GeV.

Резюме

В симметричной кварковой модели исследуются эффекты радиальной волновой функции для нестранных барионов. Вычисляются ротационные уровни энергии. Вычисленные уровни энергии хогошо согласуются с уровнями энергии в наблюденных спектрах барионных масс. Также оцениваются релятивистские пертурбационные эффекты, которые исчезают в пределе большой массы кварка. Найдена нижняя граница для мварка, которая приблизительно составляет 1.5 ГэВ.
