Description
We take into account the sigma meson cloud effect in the meson cloud model to calculate the distributions of light flavor sea quarks in the proton. Our calculation gives a better description of the data for d-bar (x)/u-bar (x). We also provide a picture that the probability of finding a physical proton in a Fock state vertical bar Nω> is reasonable small with a smaller cutoff Λω
