Description
We discuss the flavor content of the nucleon in an unquenched quark model in which the effects of quark-antiquark pairs (uu-bar, dd-bar and ss-bar) are taken into account in an explicit form. It is shown that the inclusion of qq-bar pairs leads to an excess of d-bar over u-bar quarks in the proton and to a large contribution of orbital angular momentum to the spin of the proton.
