Abstract
We consider the possibility that the soft supersymmetry-breaking parameters m1/2 and m0 of the MSSM are universal at some scale Min below the supersymmetric grand unification scale MGUT, as might occur in scenarios where either the primordial supersymmetry-breaking mechanism or its communication to the observable sector involve a dynamical scale below MGUT. We analyze the (m1/2,m0) planes of such sub-GUT CMSSM models, noting the dependences of phenomenological, experimental and cosmological constraints on Min. In particular, we find that the coannihilation, focus-point and rapid-annihilation funnel regions of the GUT-scale CMSSM approach and merge when Minâ¼1012GeV. We discuss sparticle spectra and the possible sensitivity of LHC measurements to the value of Min.
