The MSSM at the low tan β fixed point is meta-stable
We analyse the mass spectrum of the Constrained Minimal Supersymmetric Standard Model at the low tan β fixed point. We find that the model only satisfies experimental and dark matter bounds in regions where the vacuum is meta-stable – i.e. where it violates `unbounded from below' (UFB) bounds....

Summary: | We analyse the mass spectrum of the Constrained Minimal Supersymmetric Standard Model at the low tan
β fixed point. We find that the model only satisfies experimental and dark matter bounds in regions where the vacuum is meta-stable – i.e. where it violates `unbounded from below' (UFB) bounds. Adding a small amount of
R-parity violation solves these problems but the absolute upper bound on the lowest higgs mass
