Description
Leading neutron (LN) production in ep collisions at high energies is investigated using the color
dipole formalism and taking into account saturation effects. We update the treatment of absorptive
effects and estimate the impact of these effects on LN spectra in the kinematical range that will
be probed by the Electron Ion Collider (EIC) and by the Large Hadron electron Collider (LHeC).
We demonstrate that Feynman scaling, associated to saturation, is not violated by the inclusion
of absorptive effects. Moreover, our results indicate that the LN spectrum is strongly suppressed
at small photon virtualities. These results suggest that absorptive effects cannot be disregarded in
future measurements of the gamma-pi cross section to be extracted from data on leading neutron production.
