Generating the µ-term and Neutrino Mass via the Clockwork Mechanism in the Supersymmetric Standard Model

초록

In the supersymmetric standard model, generating the µ-term and neutrino mass requires large hierarchies in parameters. The clockwork mechanism is an efficient mechanism that generates an exponentially large hierarchy from the clockwork chain of couplings of order unity. In this paper, we provide supersymmetric models which utilize either the scalar or fermion clockwork mechanism to generate the µ-term and neutrino mass. These models can involve the Peccei-Quinn symmetry breaking and induce the Dine-Fischler-Srednicki-Zhitnitsky (DFSZ)-type axion model. In addition, the axino can be identified as the right-handed neutrino and thus form the mass term with the left-handed neutrino in the lepton doublet. © 2024 Korean Physical Society.
