Abstract
The static properties of the octet and decuplet baryons are considered within the framework of a quark model of hadrons where the chiral symmetry is broken dynamically through a nontrivial vacuum structure. The pion and kaon being treated consistently within the model yield to the constituent quark wave function approximately same as the wave functions from the gap equations and thus determine consequently the constituent quark field operators. The model was successfully used earlier to study some hadronic phenomena and here also it estimates the static properties of the octet and decuplet baryons in a unified manner, in reasonable agreement with the available measurements. The only parameter of the model is the harmonic oscillator radius for the baryons. The method is nonperturbative with respect to the equal time algebra for the constituent quark field operators.
