NATURAL MU-TERM WITH PECCEI-QUINN SYMMETRY

The generalized Higgs mass term NH1N2 of the supersymmetric standard m odel is used to implement the Peccei-Quinn Symmetry to solve the stron g-CP problem. Then supersymmetry breaking can generate the Higgs mass parameter mu of order m(3/2) through soft-breaking parameters. This ki nd of extension contains extra light fields of the axion supermultiple t whose dominant coupling may come from the supersymmetric axion-Higgs -Higgs coupling. We present a working example and discuss the cosmolog ical implications of the model.
