A Holographic Realization of Partially Composite Neutrinos
University of Maryland
We employ the AdS/CFT correspondence to construct the extra dimensional dual of a class of models in which the neutrinos acquire masses by mixing with the composite states of a strongly coupled hidden sector. In this framework, the light neutrinos are partially composite particles that obtain their masses from the inverse seesaw mechanism. We focus on the scenario in which the compositeness scale lies below the weak scale, leading to rich phenomenology. We explore the signals of this class of models in colliders and beam dumps, lepton flavor-violating processes and neutrinoless double beta decay. We find that the results are in good agreement with the CFT side of the correspondence.
