dc.description.abstractThe minimal supersymmetric standard model, when extended to embed the seesaw mechanism, obtains two dimensionful parameters in its superpotential: the μ parameter and the right-handed neutrino mass MN. These mass parameters, belonging to the supersymmetric sector of the theory, pose serious naturalness problems as their scales are left completely undetermined. In fact, for correct phenomenology, μ must be stabilized at the electroweak scale while MN lies at an intermediate scale. In this work we construct an explicit model of the hidden sector of N ≤ 1 supergravity for inducing both μ and MN at their right scales. The model we build utilizes lepton number conservation and continuous R invariance as two fundamental global symmetries to forbid bare μ and MN appearing in the superpotential, and induces them at phenomenologically desired scales via spontaneous breakdown of the global symmetries and the supergravity. We discuss briefly various phenomenological implications of the model.en_US
