We show the dark matter allowed region narrow blue corridor, (g-2)$_{µ}$ region (light blue) for a$_{µ}$ ≤ 11 × 10 − $^{8}$, Higgs mass ≤ 114 GeV (pink region) and LEPII bounds on SUSY masses (red). In the third panel λ = 0 . 1 were chosen, The black region is not allowed by radiative electroweak symmetry breaking, and m$_{t}$ = 172 . 7 GeV for this graph. Note that black curved lines denote the cosmological parameters, ( δ$_{H}$, n$_{s}$ ), within 95%c.l. Note that smaller values of n$_{s}$ < 1 is preferred by the dark matter abundance in this scheme of parameters. The plots are taken from [714]. Unification of gauge couplings within SUSY suggests that M$_{G}$ ≃ 2 × 10 16 GeV. The model parameters are already significantly constrained by different experimental results. Most important constraints are: (1) The light Higgs mass bound of M$_{h}$ 0 > 114 . 0 GeV from LEP [733]. (2) The b → sγ branching ratio [734]: 2 . 2 × 10 − 4 < B ( B → X$_{s}$γ ) < 4 . 5 × 10 − $^{4}$. (3) In mSUGRA the ˜ χ 0 1 is the candidate for CDM. (4) The 2 σ bound from the WMAP [13] gives a relic density bound for CDM to be 0 . 095 < Ω$_{CDM}$ h 2 < 0 . 129. (5) The bound on the lightest chargino mass of M$_{˜}$ χ ± 1 > 104 GeV from LEP [735]. (6) The possible 3 . 3 σ deviation (using e $^{+}$e − data to calculate the leading order hadronic contribution)from the SM expectation of the anomalous muon magnetic moment from the muon g − 2 collaboration [736]. The allowed mSUGRA parameter space has mostly three distinct regions: (i) the stau- neutralino (˜ τ$_{1}$ − ˜ χ 1 $_{0}$), coannihilation region where ˜ χ 1 0 is the LSP, (ii) the ˜ χ 1 0 having a dominant Higgsino component (focus point) and (iii) the scalar Higgs ( A $^{0}$, H $^{0}$) annihilation 163
