Mellin空间带电电流深度非弹性散射的$O(α_s)$重味修正

$O(α_s)$ Heavy Flavor Corrections to Charged Current Deep-Inelastic Scattering in Mellin Space

J. Blümlein, A. Hasselhuhn, P. Kovacikova, S. Moch

摘要:

我们提供了一个快速和精确的梅林空间实现的$O(α_s)$重味威尔逊系数的带电电流深度非弹性散射过程。这些结果对于中微子-核子散射中奇异夸克分布的提取和HERA带电流数据的QCD分析具有重要意义。纠正了文献中的错误。我们还讨论了Mellin空间中一系列更一般的部分子参数化。

英文摘要:

We provide a fast and precise Mellin-space implementation of the $O(α_s)$ heavy flavor Wilson coefficients for charged current deep inelastic scattering processes. They are of importance for the extraction of the strange quark distribution in neutrino-nucleon scattering and the QCD analyses of the HERA charged current data. Errors in the literature are corrected. We also discuss a series of more general parton parameterizations in Mellin space.
