Query: Neutralino Cold Dark Matter in a One Parameter Extension of the Minimal
  Supergravity Model   Within the minimal supergravity model (mSUGRA) framework, the expectation for
the relic density of neutralinos exceeds the WMAP determination unless
neutralinos a) have a significant higgsino component, b) have a mass close to
half that of a heavy Higgs boson, or c)can efficiently co-annihilate with a
charged or colored particle. Within a 1-parameter extension of the mSUGRA model
which includes non-universal Higgs masses, we show that agreement with the WMAP
data can be obtained over a wide range of mSUGRA parameters for scenarios a)
and b), so that the phenomenological implications may be much more diverse than
in mSUGRA. We show that direct and/or indirect detection of neutralino dark
matter should be possible at various current and planned facilities.
