包含纵向结构函数的低Q^2结构函数

Low Q^2 Structure Functions including the Longitudinal Structure Function

Shima Shimizu

摘要:

用H1和ZEUS合作的2000年的数据对HERA组合截面进行了NLO QCD分析,得到了明显改善的部分子分布函数. 2007年,HERA成功地以降低的质心能量运行。在x \sim 10^{-3}处进行了F_L的直接测量,给出了描述质子结构的微扰QCD框架的一个很好的检验。

英文摘要:

An NLO QCD analysis on the HERA combined cross sections obtained from the measurements using the data up to the year 2000 at both the H1 and ZEUS collaborations provides significantly improved parton distribution functions. In 2007, HERA successfully operated with reduced center-of-mass energies. Direct measurements of F_L were performed at x\sim10^{-3}, giving a good test of the perturbative QCD framework in describing proton structure.
