1. The meson cloud and the strange form factors of the proton / A nuvem mesônica e os fatores de forma estranhos do próton
The goal of this work was to include the scalar $\kappa$ meson on the meson cloud of the proton, and then to verify if the strangeness contribution to the electromagnetic properties of the proton could be explained by the meson cloud model. The observables that quantify such a contribution are the electric ($G_E^s$) and magnetic ($G_M^s$) strange form factor

2. The pion electromagnetic form factor in the meson cloud model
In this work we calculate the meson cloud effects on the pion electromagnetic form factor and perform a comparison with experimental data. We show that, even though the cloud is not the only non-perturbative process to be considered, its contribution is significant. We also study the influence of the cutoff choices on the results.
