| 英文摘要 | Experimentally, the production of oppositely charged dimuon events by neutrino and antineutrino deep inelastic scattering (DIS) is used to determine the strangeness asymmetry inside a nucleon. Here we point out that the direct production of a D-meson in DIS may have a substantial influence on the measurement of nucleon strangeness distributions. Direct D-meson production is via heavy quark recombination (HQR) and via light-quark fragmentation from perturbative QCD (LQF-P). To see the influence precisely, we compute the direct D-meson productions via HQR and LQF-P quantitatively and estimate their corrections to the analysis of the strangeness asymmetry. The results show that HQR has a stronger effect than LQF-P does, and the former may influence the experimental determination of the nucleon strangeness asymmetry. |
