The shapes of baryons in constrained potential models

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

Summary

We examine the equilibrium shapes of the system of 3 quarks subject to a potential and to a variety of constraints, some of which have been used in the literature. Both relativistic and nonrelativistic dynamics are considered. The results indicate that realistic calculations of the baryon spectrum should be arranged so as to allow for considerable departures from the spherical shape of the system. The results of the assumption that quarks move in a potential of constant volume are compared with those of some other assumptions. Although the models used are very simple they do show the tendency to produce some of the observed level patterns of the baryon mass spectrum.

Riassunto

Si esaminano le forme di equilibrio di un sistema di 3 quark soggetto a un potenziale e a vari vincoli, alcuni dei quali sono stati usati in letteratura. Si considera la dinamica relativistica e non relativistica. I risultati indicano che i calcoli realistici dello spettro barionico dovrebbero essere stabiliti in modo da permettere di allontanarsi in modo considerevole dalla forma sferica del sistema. Si confrontano i risultati dell'assunto che i quark si muovono in un potenziale di volume costante con quelli di altri assunti. Sebbene i modelli usati siano molto semplici, mostrano la tendenza a produrre alcuni dei modelli dei livelli osservati dello spettro di massa barionica.
