Query: Bounding resonant Majorana neutrinos from four-body B and D decays   Searches of lepton-number violation in different processes are very useful to
constrain the parameter space of Majorana neutrinos. Here we use available
upper bounds on the branching fractions of B^- -> D^0pi^+mu^-mu^- and D^0 ->
(pi^-pi^-/K^-pi^-) mu^-mu^- decays to derive constraints on the mass and
mixings of Majorana neutrinos by assuming they are produced resonantly in these
four-body decays. While the excluded region obtained from B^- decays are
competitive with existing limits from three-body D^- and B^- decays, it is
shown that experimental improvements on D^0 decays offer a good potential to
provide similar results.
