Abstract
We present a detailed discussion of the lepton flavour and number violating conversion of bound muons into positrons. This process is a viable alternative to neutrinoless double beta decay and, given that experiments on ordinary $\mu^-$- $e^-$ conversion are expected to improve their sensitivities by several orders of magnitude in the coming years, we can also assume the limit on $\mu^-$- $e^+$ conversion to improve by roughly the same factor. We discuss how new physics at a high scale can lead to short-range contributions to this conversion process and we present one explicit case in great detail (the single one for which the corresponding nuclear matrix elemen...
