abstract
Neutrinos can have naturally small Dirac masses if the Standard Model singlet right-handed neutrinos are light composite fermions. Theories which produce light composite fermions typically generate many of them, three of which can marry the left-handed neutrinos with small Dirac masses. The rest can serve as sterile states which can mix with the Standard Model neutrinos. We present explicit models illustrating this idea.

Partial compositeness with inverse seesaw yields neutrino dipole moments of 10^{-6} to 10^{-8} GeV^{-1} and predicts single- and multi-photon radiative signals at MiniBooNE and MINERvA.
