Interference effects in LNV and LFV semileptonic decays: the Majorana hypothesis

Abstract In the case where the Standard Model is extended by one heavy Majorana fermion, the branching fractions of semileptonic meson decays into same-sign and opposite-sign dileptons are expected to be of the same order. As we discuss here, this need not be the case in extensions by at least two s...
