In this approach, it is discussed the relevance of the quark-antiquark pair terms for the full covariance of the e.m. current. It is also verified, by considering a QCD dynamical model, that a good agreement with experimental data can be obtained for the kaon weak decay constant once a probability of about 80% of the valence component is taken into account.610C-613CengArtigo10.1016/j.nuclphysa.2007.03.103WOS:000248297600118Acesso restrito
