Domain Walls with Massive Hypermultiplets
Domain walls play a central role in a subject of recent interest, the braneworld scenario. In particular, BPS domain walls are investigated in detail in D = 4, N = 1 SUSY theories. We should consider hypermultiplets to realize D = 4, N = 1 SUSY theory on the world-volume. In order to have a potential with discrete degenerate vacua, they must have gauge interaction, or nonlinearity of kinetic te...
متن کاملWeak Scale Inflation and Unstable Domain Walls
Cosmlogical domain walls produced during phase transition are expected to collapse on a cosmologically safe timescale if Vilenkin’s condition is satisfied. We show that the decaying processes of these unstable domain walls should be changed significantly if weak scale inflation takes place. The usual condition for the safe decay of the cosmological domain wall must be changed, depending on thei...
متن کاملThermal inflation, baryogenesis and axions
In a previous paper, we proposed a simple extension of the Minimal Supersymmetric Standard Model which gives rise to thermal inflation and baryogenesis in a natural and remarkably consistent way. In this paper, we consider the λφ = 0 special case of our model, which is the minimal way to incorporate a Peccei-Quinn symmetry. The axino/flatino becomes the lightest supersymmetric particle with mã ...
متن کاملDomain Walls and Massive Gauged Supergravity Potentials
We point out that massive gauged supergravity potentials, for example those arising due to the massive breathing mode of sphere reductions in M-theory or string theory, allow for supersymmetric (static) domain wall solutions which are a hybrid of a RandallSundrum domain wall on one side, and a dilatonic domain wall with a run-away dilaton on the other side. On the anti-de Sitter (AdS) side, the...
متن کاملFormation of monopoles and domain walls after brane inflation
We study cosmological defect formation induced by brane creation after brane inflation. Contrary to the previous arguments, production of monopoles and domain walls are not negligible. Monopoles and domain walls are formed by the creation of daughter branes that are extended between mother branes.
