Coordinate Space Distributions of Antiquark Flavor Asymmetries in the Proton

We examine the space-time properties of the distribution (dbar - ubar) and dbar/ubar in the proton. The difference of the antiquark distributions shows the expected peak at the approximate pion Compton wavelength and is supportative of the thesis that the meson cloud of the nucleon is at the origin of the asymmetry of (dbar - ubar), with the pion cloud playing a dominant role.
