We study the effect of the meson cloud dressing in the octet baryon todecuplet baryon electromagnetic transitions. Combining the valence quarkcontributions from the covariant spectator quark model with those of the mesoncloud estimated based on the flavor SU(3) cloudy bag model, we calculate thetransition magnetic form factors at $Q^2=0$ ($Q^2=-q^2$ and $q$ thefour-momentum transfer), and also the decuplet baryon electromagnetic decaywidths. The result for the $\gamma^\ast \Lambda \to \Sigma^{\ast 0}$ decaywidth is in complete agreement with the data, while that for the $\gamma^\ast\Sigma^+ \to \Sigma^{\ast +}$ is underestimated the data by 1.4 standarddeviations. This achievement may be regarded as a significant advance in thepresent theoretical situation.

What is the role of the meson cloud in the $\Sigma^{*0} \to \gamma \Lambda$ and $\Sigma^\ast \to \gamma \Sigma$ decays?
