Descripción: We study the <math>\bar{d}- \bar{u}\,\!</math> asymmetry of the proton in a model approach in which hadronic fluctuations of the nucleon are generated through gluon splitting and recombination mechanisms. Within this framework, it is shown that the <math>\bar{d}- \bar{u}\,\!</math> asymmetry of the proton is consistently described by including only nucleon fluctuations to <math>|\pi N \rangle> \,\!</math> and <math>|\pi \Delta\rangle\,\!</math> bound states. Predictions of the model closely agree with the recent experimental data of the E866/NuSea Collaboration.
