000030109 520__ $$aWe study the four-body decays of neutral flavored mesons, including , D0, , and . These processes, which could be induced by a hypothetical doubly-charged scalar particle, do not conserve the lepton number. Assuming, as an example, that the mass of the doubly-charged particle is 1000 GeV, and using the upper bounds of the couplings, we calculate the branching ratios of different channels. For , , and , it is of the order of 10−30, 10−32–10−29, and 10−33–10−28, respectively. Based on the experimental results for the  channels, we also find the upper limit for the quantity .
