Influence of heavy-quark recombination on the nucleon strangeness asymmetry
Influence of heavy-quark recombination on the nucleon strangeness asymmetry
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 …
