The DIS dipole picture cross section at finite energy

Abstract

We implement a finite energy constraint in the dipole picture of deep inelastic scattering, by restricting the invariant mass of the produced partonic system by the virtual photon-target center of mass energy. We show that, for $Q^2=1$GeV${}^2$, the effect of this constraint can reach up to $\sim$35\% for charm quarks and $\sim$7\% for light quarks at $x=0.01$, but then rapidly decreases at smaller $x$ or larger $Q^2$.
