The MSSM at the low tanβ fixed point is meta-stable

We analyse the mass spectrum of the Constrained Minimal Supersymmetric Standard Model at the low tan beta 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 m(h)o < 97 GeV remains. We present the predicted sparticle mass spectrum as a function of the gluino mass m(g). (C) 1998 Elsevier Science B.V. All rights reserved.
