Impact of Inclusive Electron Ion Collider Data on Collinear Parton Distributions
arXiv (Cornell University)(2023)
摘要
A study is presented of the impact of simulated inclusive Electron Ion
Collider Deep Inelastic Scattering data on the determination of the proton and
nuclear parton distribution functions (PDFs) at next-to-next-to-leading and
next-to-leading order in QCD, respectively. The influence on the proton PDFs is
evaluated relative to the HERAPDF2.0 set, which uses inclusive HERA data only,
and also relative to the global fitting approach of the MSHT20 PDFs. The impact
on nuclear PDFs is assessed relative to the EPPS21 global fit and is presented
in terms of nuclear modification ratios. For all cases studied, significant
improvements in the PDF uncertainties are observed for several parton species.
The most striking impact occurs for the nuclear PDFs in general and for the
region of high Bjorken x in the proton PDFs, particularly for the valence
quark distributions.
