Hypercentral Constituent Quark Model and Isospin for the Baryon Static Properties

Abstract

So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have taken into account the three body force effect and standard two-body potential contributions. According to our model the static properties of hadrons containing u, d, and s quarks are better than the other models and closer to the experiment. The two key ingredients of this improvement are the effective quark-gluon hypercentral potentials, the hyperfine interaction and isospin-dependence potential.
