WIMP Dark Matter and Neutrino Mass from Peccei-Quinn Symmetry
The Peccei-Quinn anomalous global U(1)PQ symmetry is important for solving the strong CP problem with a cosmologically relevant axion. We add to this the simple (but hitherto unexplored) observation that it also has a residual Z2 symmetry which may be responsible for a second component of dark matter, i.e. an absolutely stable weakly interacting singlet scalar. This new insight provides a theor...
متن کاملFlatons and Peccei-quinn Symmetry
We study in detail a supersymmetric Peccei-Quinn model, which has a DFSZ and a KSVZ version. The fields breaking the Peccei-Quinn (PQ) symmetry correspond to flat directions (flaton fields) and have unsuppressed couplings when PQ symmetry is unbroken. The models have interesting particle physics phenomenology. The PQ scale is naturally generated through radiative corrections; also, in the DFSZ ...
متن کاملNatural Μ-term with Peccei-quinn Symmetry
The generalized Higgs mass term NH1H2 of the supersymmetric standard model is used to implement the Peccei-Quinn Symmetry to solve the strongCP problem. Then supersymmetry breaking can generate the Higgs mass parameter μ of order m3/2 through soft-breaking parameters. This kind of extension contains extra light fields of the axion supermultiplet whose dominant coupling may come from the supersy...
متن کاملAxions and a Gauged Peccei-Quinn Symmetry
The axion solution to the strong CP problem requires an anomalous global U(1) symmetry. We show that the existence of such a symmetry is a natural consequence of an extra dimension in which a gauged U(1) is spontaneously broken on one of two branes, leaving an accidental global symmetry on the other brane. Depending on where the standard model matter lives, the resulting axion can be either the...
متن کاملThe Peccei–Quinn Field as Curvaton
A simple extension of the minimal supersymmetric standard model which naturally and simultaneously solves the strong CP and μ problems via a PecceiQuinn and a continuous R symmetry is considered. This model is supplemented with hybrid inflation and leptogenesis, but without taking the specific details of these scenarios. It is shown that the Peccei-Quinn field can successfully act as a curvaton...
