  In mSUGRA models the lightest supersymmetric particle (assumed to be the
lightest neutralino) provides an excellent cold dark matter (CDM) candidate.
The supersymmetric parameter space is significantly reduced, if the limits on
the CDM relic density, obtained from WMAP data, are used. Assuming a vanishing
trilinear scalar coupling A0 and fixed values of tan(beta), these limits result
in narrow lines of allowed regions in the m0-m12 plane, the so called WMAP
strips. In this analysis the trilinear coupling A0 has been varied within
+/-4TeV resulting in largely extended areas in the m0-m12 plane which are no
longer excluded.
