We perform a likelihood analysis of the constraints from accelerator experiments and astrophysical observations on supersymmetric (SUSY) models with SU(5) boundary conditions on soft SUSYbreaking parameters at the GUT scale. The parameter space of the models studied has seven parameters: a universal gaugino mass $$m_{1/2}$$m1/2, distinct masses for the scalar partners of matter fermions in five and tendimensional representations of SU(5), $$m_5$$m5 and $$m_{10}$$m10, and for the $$\mathbf {5…

A likelihood analysis of the minimal anomalymediated supersymmetrybreaking (mAMSB) model is performed and it is found that either a winolike or a Higgsinolike neutralino LSP, may provide the cold dark matter (DM), both with similar likelihoods.
