Nucleon Strange Asymmetry and the Light Quark Fragmentation Effect

  • Nucleon strange asymmetry is an important non-perturbative effect in the study of nucleon structure, but it has not been checked by experiments yet.For effectively measuring the nucleon strange asymmetry,we investigate the light quark fragmentation effect that may affect the measurement of the strange asymmetry.We suggest an inclusive measurement of charged and neutral charmed hadrons by using an emulsion target in the neutrino and antineutrino induced charged current deep inelastic scattering, in which the strange asymmetry effect and the light quark fragmentation effect can be separated.

Abstract: Nucleon strange asymmetry is an important non-perturbative effect in the study of nucleon structure, but it has not been checked by experiments yet.For effectively measuring the nucleon strange asymmetry,we investigate the light quark fragmentation effect that may affect the measurement of the strange asymmetry.We suggest an inclusive measurement of charged and neutral charmed hadrons by using an emulsion target in the neutrino and antineutrino induced charged current deep inelastic scattering, in which the strange asymmetry effect and the light quark fragmentation effect can be separated.
