Abstract

The two-photon contribution to deep inelastic lepton-nucleus scattering is investigated. The resulting contribution is of the order of a few percent of the ratio of the lepton-nucleus cross section per nucleon divide by the lepton-proton cross section, and is restricted to the lowest kinematically allowed values of the proton scaling variable X_lp. The calculated effect is presented as a function of the nucleus charge Z, the incoming lepton laboratory energy E_lab, and momentum transfer squared Q². The γγ contribution increases with Z and with E_lab for fixed Q².
