Despite the great experimental efforts, we have not yet found a positive signal of its interactions with ordinary matter. One possible explanation would be that the dark matter particle is primarily coupled to another elusive particle, neutrinos. In this work we study this possibility with several realisations.","authors_text":"A. Olivares-Del Campo, A. V. Titov, E. Fern\\'andez-Mart\\'inez, M. Blennow, S. Pascoli, S.
