Peccei-Quinn extended gauge-mediation model with vector-like matter and 125 GeV Higgs

摘要

We construct a gauge-mediated SUSY breaking model with vector-like matters combined with the Peccei-Quinn mechanism to solve the strong CP problem. The Peccei-Quinn symmetry plays an essential role for generating sizable masses for the vector-like matters and the μ-term without introducing dangerous CP angle. The model naturally explains both the 125 GeV Higgs mass and the muon anomalous magnetic moment. The stabilization of the Peccei-Quinn scalar and the cosmology of the saxion and axino are also discussed.
