Resumen:
We point out that perturbative evolution in QCD at three loops generates a strange-antistrange asymmet rys in the nucleon’s sea just f rom the fact that the nucleon has nonvanishing up and down quark valence densities. The recently computed three- loop splitting funct ions allow for an est imate of this effect. We find that a fairly sizable asymmetry may be generated.
