Extracting the Proton Structure Function Moments from World Data

We present an extraction of the lowest three moments of the proton structure functions $F_L$ and $F_2$ from available world data between $Q^2$ = 0.75 and 45.0 (GeV/c)$^2$. This analysis leverages in particular new data from DESY at low Bjorken $x$ and from Jefferson Lab at high $x$, allowing the moments to be determined relatively free from uncertainties due to extrapolations into unmeasured regions. The moments are compared with several parton distribution function parameterizations.
