Showed potential of neutrino experiments to constrain Elko-neutrino interactions.

Provided theoretical bounds on interaction strength and Elko properties.

Abstract

We analyze the potential of accelerator-based neutrino experiments, such as the Deep Underground Neutrino Experiment, to constrain a five dimensional operator mediating a beyond standard model interaction between mass dimension one fermion fields, labeled elko, and neutrino. We identify the parameter space where elko is a viable dark matter candidate.
