论文摘要
我们讨论了NCTEQ方法中核部分分布功能的两个最新全球分析。 $ W/z $ -BOSON，单包重强子和重型夸克/夸克产量的LHC数据不仅可以显着将Gluon的不确定性显着降低至$ x \ geq10^{ - 5} $，而且还会影响奇怪的夸克密度。后者进一步限制了中微子深弹性散射和魅力dimuon的生产数据，其与中性气流实验的一致性也得到了重新评估。
We discuss the two most recent global analyses of nuclear parton distribution functions within the nCTEQ approach. LHC data on $W/Z$-boson, single-inclusive hadron and heavy quark/quarkonium production are shown to not only significantly reduce the gluon uncertainty down to $x\geq10^{-5}$, but to also influence the strange quark density. The latter is further constrained by neutrino deep-inelastic scattering and charm dimuon production data, whose consistency with neutral-current experiments is also re-evaluated.
