摘要The nucleon strange and antistrange distribution asymmetry is an important issue in the study of the nucleon structure. In this work, we show that the heavy- quark recombination processes from a perturbative QCD picture can give a sizable influence on the measurement of the nucleon strangeness asymmetry from charged- current charm production processes, such as the CCFR and NuTeV dimuon measurements. When the influence of heavy- quark recombination is considered, a positive effective delta S(HR)(-) should be added to the initially extracted strangeness asymmetry S(-) equivalent to integral dx [s (x ) - (S) over bar (x)] x, supporting the strangeness asymmetry S(-) being positive, which is helpful to explain the NuTeV anomaly within the framework of the standard model.
