摘要:

我们提出了一个改进的确定奇怪的海分布的核子与约束来自最近的粲生产数据的中微子核子深度非弹性散射的NOMAD和CHORUS实验和带电电流包容的深度非弹性散射在HERA。我们证明了这些结果与ATLAS和CMS关于$W^\pm$ -玻色子与$c$ -夸克的关联产生的实验数据是一致的。我们还讨论了有关的问题,最近的奇怪的海确定的ATLAS实验使用LHC对撞机数据。

英文摘要:

We present an improved determination of the strange sea distribution in the nucleon with constraints coming from the recent charm production data in neutrino-nucleon deep-inelastic scattering by the NOMAD and CHORUS experiments and from charged current inclusive deep-inelastic scattering at HERA. We demonstrate that the results are consistent with the data from the ATLAS and the CMS experiments on the associated production of $W^\pm$-bosons with $c$-quarks. We also discuss issues related to the recent strange sea determination by the ATLAS experiment using LHC collider data.
