The Hong-Ou-Mandel (HOM) and Hanbury Brown and Twiss (HBT) experiment show second-order interference of independent photons. Both rely on the bosonic nature of indistinguishable photons and commutator relations upon exchange of bosons[1]. HBT-/HOM- like experiments have also been conducted with massive bosonic/ fermionic particles like atoms, for which the effects are likewise well understood [3,4]. However, though electrons, in some settings, attain an imaging resolution far beyond the one achieved with photons, investigations of higher-order correlations of electrons have been scarce. We develop a model describing the spatio-temporal two-electron correlations for statistically independent electron sources. Contrary to (neutral) atoms, Coulomb-interaction must be taken into account, requiring full treatment of the particle-particle interaction. The methods used to solve this problem stem from scattering theory in non-relativistic quantum mechanics. Result is a predictive model waiting for experimental tests. [1] R. J. Glauber, Phys.
