Description
Recently, the $Q^2$ dependence of several low moments of the proton longitudinal structure function, $F_L$, has been mapped thanks to the measurements taken at HERA and JLAB. In this contribution, we present the first lattice QCD determination of the lowest moment of $F_L$ and its $Q^2$ dependence. This is achieved by computing the forward Compton amplitude via an application of the second-order Feynman-Hellmann method. We show the moments of $F_1$, $F_2$, and $F_L$ in comparison to experimental values and discuss future directions.
