Query: Bound-state dark matter and Dirac neutrino mass   We propose a simple theory for the idea that cosmological dark matter (DM)
may be present today mainly in the form of stable neutral hadronic thermal
relics. In our model neutrino masses arise radiatively from the exchange of
colored DM constituents, giving a common origin for both dark matter and
neutrino mass. The exact conservation of $B-L$ symmetry ensures dark matter
stability and the Dirac nature of neutrinos. The theory can be falsified by
dark matter nuclear recoil direct detection experiments, leading also to
possible signals at a next generation hadron collider.
