论文摘要
我们使用对重味梅森[D0，J/PSI，J/PSI（1SSILON（1S）]在LHC的LHC中未使用这些原始确定的原始确定的proton-Lead碰撞中的生产中的两套核PDFS NCTEQ15和EPPS16的核PDF [D0，J/PSI，J/PSI]的选择。由于这些新的重量限制，重新持续的PDF表现出明显较小的不确定性。我们与LHC和RHIC的另一系列数据进行了比较，这些数据未包括在我们的重新加权程序中。总体上比较非常好，可以作为对这些重新加权的核PDF集的验证，我们将其列为NCTEQ15_RWHF＆EPPS16_RWHF。这表明可以在标准的共线分解框架内描述LHC和正向RHIC重量数据数据，并具有相同的（通用）小X Gluon分布。我们讨论如何使用此类重量的PDF以及我们的程序的局限性。
We present the reweighting of two sets of nuclear PDFs, nCTEQ15 and EPPS16, using a selection of experimental data on heavy-flavor meson [D0, J/psi, J/psi from B and Upsilon(1S)] production in proton-lead collisions at the LHC which were not used in the original determination of these nuclear PDFs. The reweighted PDFs exhibit significantly smaller uncertainties thanks to these new heavy-flavor constraints. We present a comparison with another selection of data from the LHC and RHIC which were not included in our reweighting procedure. The comparison is overall very good and serves as a validation of these reweighted nuclear PDF sets, which we dub nCTEQ15_rwHF & EPPS16_rwHF. This indicates that the LHC and forward RHIC heavy-flavor data can be described within the standard collinear factorization framework with the same (universal) small-x gluon distribution. We discuss how we believe such reweighted PDFs should be used as well as the limitations of our procedure.
