The pre-dominance of ordinary matter over anti-matter in the observable universe is one of the major unsolved questions of cosmology. Without this so-called baryon asymmetry (BA) the universe would be a void. An avenue to explain BA is through the discovery of a process that violates the number of leptons (LNV). Prime candidate is the neutrinoless double beta decay (0n2b). While in ordinary double beta decays (2n2b) two nucleons simultaneously decay in two charged leptons and two neutrinos, in 0n2b the neutrinos are internally absorbed leading to LNV. In most theories this is connected to the notion of Majorana fermions (MF), i.e. the neutrino being its own anti-matter partner. Neither LNV…
