摘要:

利用一组空间相关的核PDF EPS09s研究了LHC上p+Pb碰撞中包含的中性π介子和瞬发光子核修正因子的中心依赖性。计算在中期和前向快速搜索一个观察,这将最佳地探测核PDF的空间依赖性。此外,我们还讨论了不同观测量对原子核的哪些$x$值敏感。

英文摘要:

The centrality dependencies of the inclusive neutral pion and prompt photon nuclear modification factors for p+Pb collisions at the LHC are studied using a spatially dependent set of nuclear PDFs, EPS09s. The calculations are performed at mid- and forward rapidities searching for an observable which would optimally probe the spatial dependence of the nuclear PDFs. In addition, we discuss to which $x$ values of the nucleus the different observables are sensitive.
