从HERA到LHC的质子结构

Proton Structure from HERA to LHC

Amanda Cooper-Sarkar

摘要:

大型强子对撞机实验所覆盖的运动学区域探测了Bjorken- $x$的低值。在与$W$和$Z$产生相关的尺度上,中心快度区覆盖了$10^{-3} < x < 10^{-1}$。这意味着HERA的数据对大型强子对撞机运行早期阶段的部分子分布函数(PDF)的行为提供了最深入的了解。H1和ZEUS实验正在结合它们的数据,以提供HERA结果的遗产。目前的数据组合和这些数据的影响,我们的知识的部分子分布函数进行了探讨。

英文摘要:

The kinematic region covered by the LHC experiments probes low values of Bjorken-$x$. At the scale relevant for $W$ and $Z$ production the central rapidity region covers $10^{-3} < x < 10^{-1}$. This means that it is the HERA data which give the most insight into the behaviour of parton distribution functions (PDFs) for the early phase of running at the LHC. The H1 and ZEUS experiments are combining their data so as to provide a legacy of HERA results. The present status of the data combinations and the impact of these data on our knowledge of parton distribution functions is explored.
