Abstract: Lepton number violation (LNV) as underlying neutrinoless nuclear double beta decay (DBD) and equal-charged lepton pair plus di-jet production in ultra-relativistic hadron collisions are expected to deliver the heavily searched on signatures for physics beyond the standard model (BSM). Direct probes for LNV are lepton DCE (LDCE) reactions at accelerators, apparently and surprisingly never considered before. Theoretical concepts are discussed, merging into a second order approach. As a first application. total cross sections of $\Delta L=+2$ (e-,e+) reactions on nuclear targets are estimated [1,2]. At beam energies beyond 10 GeV, cross sections of magnitudes are predicted which might be
measurable at existing facilities.
