Abstract

In the present work, we explore the effect of the meson cloud dressing on the octet and decuplet baryon masses within the perturbative chiral quark model by considering both the ground and excited quark propagators, in which the excited states in the quark propagators are truncated up to the low energy scale \(\Lambda = 1\) GeV. The total results on the octet and decuplet baryon masses agree excellently with the experimental data. The study also clearly shows that the meson cloud plays an important role in the baryon mass, and the excited states in the intermediate quark propagators are significantly influential.
