NuTeV Anomaly and Strange Quark-antiquark Asymmetry
-
摘要: 总结了利用核子内的奇异夸克反奇异夸克不对称性来解释NuTeV反常的工作，表明奇异夸克反奇异夸克不对称性可作为解释NuTeV反常的一种合理机制，也说明了NuTeV反常现象也可能是对奇异夸克反奇异夸克不对称性的一种支持。This talk summarized the results of using strange quark-antistrage quark asymmetry of the nucleon to explain the NuTeV anomaly. It is shown that asymmetric strange quark-antistrage quark distributions may be a reasonable explanation for the NuTeV defect. On the other side, the NuTeV anomaly could be the evidence for the existence of asymmetric strange-antistrange quark distributions.Abstract: This talk summarized the results of using strange quark-antistrage quark asymmetry of the nucleon to explain the NuTeV anomaly.
