Neutralino Dark Matter in 2005.

I summarize some recent work on supersymmetric neutralinos as candidates for cold Dark Matter in the Universe. This includes a new scan of mSUGRA parameter space, with special emphasis on neutralinos annihilating predominantly through exchange of the light CP-even Higgs boson, and on bounds on sparticle masses. Next, prospects of testing models with TeV higgsino-like Dark Matter at colliders are discussed. Finally, I briefly comment on extensions of the mSUGRA model, and on scenarios with non-standard cosmology. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
