在最高$Q^2$深度非弹性散射下探测QCD

Probing QCD at the Highest $Q^2$ Deep Inelastic Scattering

J. Ferrando

摘要:

最近的结果从HERA EP对撞机审查在这些会议记录。这些结果来自于在高能尺度下探测QCD的测量,如$Q^2$所定义的,四个动量转移平方的碰撞。这些横截面测量提供了关于质子的部分子分布函数(PDF)的信息,并且可以用于约束这些PDF的全局拟合。最近的测量强耦合$α_S$和射流子结构从HERA在类似的能量尺度进行了审查。

英文摘要:

Recent results from the HERA ep collider are reviewed in these proceedings. The results are from measurements that probe QCD at high-energy scales, as defined by $Q^2$, the four-momentum-transfer squared of the collisions. These cross-section measurements provide information about the parton distribution functions (PDFs) of the proton and can be used to constrain global fits of these PDFs. Recent measurements of the strong coupling $α_S$ and jet substructure from HERA at similar energy scales are also reviewed.
