Abstract

We present a global fit to the structure function F₂ measured in lepton-proton experiments at small values of Bjorken-x, x< 0.01, for all experimentally available values of Q², 0.045< Q² < 800 GeV², using the Balitsky -Kovchegov equation including running coupling corrections. Using our fits to F₂, we reproduce available data for F_L and perform predictions, parameter-free and completely driven by small-x evolution, to the kinematic range relevant for the LHeC.
