We compute the light antiquark flavor asymmetry in the proton using the Chiral Quark Model (χ\rm QM). The distribution functions for the light antiquarks d(x) and u(x) have been extracted with the help of experimental data from NuSea/E866 and HERMES for the Bjorken-x range 0.015 < x < 0.35 as well from the most recent SeaQuest data for an extended x range 0.13 < x < 0.45. Our results on the d(x)-u(x), \fracd(x)u(x) and Gottfried Integral IG are in agreement with the experimental data and confirm the presence of enhanced d sea whose origin is purely non-perturbative based on chiral symmetry breaking in QCD.
