论文摘要
由于其正向覆盖范围,LHCB可以以高精度探测质子和核的价夸克分布。该程序介绍了Z玻色子生产的新的LHCB测量,该测量与质子质子碰撞的正向区域以及质子铅碰撞中的Z Boson产生相关。 Z+Charm Jet的产生可能对质子波函数中类似价的内在链分量敏感。质子铅碰撞中Z产生的测量值对核内核子的核心结构有了新的约束。还讨论了结果与Parton分布功能之间的比较。
Because of its forward coverage, LHCb can probe the valence quark distributions of protons and nuclei at small and large Bjorken-x with high precision. This proceeding presents new LHCb measurements of Z boson production in association with charm jet in the forward region of proton-proton collisions and Z boson production in proton-lead collisions. Z+charm jet production could be sensitive to a valence-like intrinsic-charm component in the proton wave function. The measurements of Z production in proton-lead collisions provide new constraints on the partonic structure of nucleons inside nuclei. Comparisons between the results and calculations with parton distribution functions are also discussed.
