NuTeV Anomaly Versus Strange-Antistrange Asymmetry

Original · EN

We report the correction from the asymmetric strange-antistrange sea of the nucleon by using both the light-cone baryon-meson fluctuation model and the chiral quark model, and show that a significant part of the NuTeV anomaly can be explained by the strange-antistrange asymmetry. We also show that the calculated s/s asymmetry are compatible with the NuTeV data by including some additional symmetric s/s quark contribution.
