... cases

Models with non-universal Higgs masses at the GUT scale can give instances of exceptions to this generic spectral pattern, featuring light first and second generation sfermions (see e.g. Baer et al. 2005b,2005c).

... bosons

The direct annihilation into photons is loop suppressed in supersymmetric models (see e.g. Bergstrom & Snellman 1988; and Bergstrom & Ullio 1997).

... density

We adjusted here the values of m₀ given in Battaglia et al. (2004) in order to fulfill this requirement making use of the latest Isajet v.7.72 release and of the DarkSUSYpackage (Edsjo et al. 2003, see Table 1).

We scan all the SUSY parameters linearly over the indicated range.

... masses

Since we do not impose any gaugino unification relation, we do not impose any constraint from collider searches on the neutralino sector.
