HERA强耦合的确定

Determinations of the Strong Coupling at HERA

Thomas Schoerner-Sadenius

摘要:

综述了HERA QCD耦合常数α的测定现状。由于喷流的最终状态提供了最相关的输入HERA确定阿尔法,相关的方法和结果从喷流物理进行了讨论。此外,HERA和阿尔法值的世界平均值。最后,介绍了HERA-PDF 1.6质子部分子分布函数集,它也使用喷流末态数据。

英文摘要:

The status of determinations of the QCD coupling constant, alphas, at HERA is reviewed. Since jet final states provide the most relevant input to the HERA determinations of alphas, the relevant methods used in and results from jet physics are also discussed. Furthermore, HERA and world averages of alphas values are presented. Finally, the HERA-PDF 1.6 proton parton distribution function set which also uses jet final-state data is introduced.
