论文摘要
我回顾了对质子和核的低X partononic含量研究的最新发展，重点是后者，因为在这种情况下，人们期望与线性QCD进化的偏差最为明显。我举例说明了HERA测量的最新理论描述，重点是BFKL进化的作用。然后，我专注于核PDF的状态和假设，以及在LHC上使用正向颗粒产生的可能性，特别是对开放式魅力的测量和电磁探针的潜力。
I review recent developments in the study of the low-x partonic content of protons and nuclei, with a focus on the latter, as one expects possible deviations from linear QCD evolution to be most pronounced in that case. I give examples of recent theoretical descriptions of HERA measurements with a focus on the role of BFKL evolution. I then concentrate on the status and assumptions of nuclear PDFs and the possibility to use forward particle production at the LHC as further constraint, in particular measurements of open charm and the potential of electromagnetic probes.
