      abstract     = {Various kinds of physics phenomena can be probed by
                      electron scattering fixed target experiments. Recently,
                      fixed target experiments investigating the reaction $e(A, Z)
                      → e(A, Z)l^{+} l^−$ , where (A, Z) denotes a nucleus of
                      atomic number Z, were utilized to search for physics beyond
                      the Standard Model at modest energies. In these experiments
                      a search for a small, narrow resonance in the invariant mass
                      spectrum of the lepton-antilepton pair, arising from the
                      exchange of a new light gauge boson γ coupling to the dark
                      sector as well as very weakly to standard model particles,
                      is performed. Such a signal would appear as an enhancement
                      over a smooth QED background, which therefore requires a
                      precise understanding of the background. We present a
                      theoretical analysis of the cross sections describing this
                      process, which are then used to extract exclusion limits on
                      the parameter space of the $\gamma´$ , and compare our
                      results to existing experimental data taken at MAMI.},
