Abstract
Flavor symmetric sea quarks could contribute to the ratio of 
in the proton, as well as flavor asymmetric sea quarks. We clarify the isoscalar mesonic contribution, especially σ meson cloud effects in the meson cloud model. We also provide the meson numbers in the proton with different meson cutoff values. Our calculations show that a physical proton picture favors smaller cutoff of the examined range 1.0<Λω<1.5GeV.
