We have made a very accurate calculation of the relic density of neutralino dark matter in the minimal supergravity framework. This calculation includes all so-called coannihilations and it uses the DarkSUSY package. In agreement with earlier analyses, we find that coannihilations have a huge effect on the density and this extends the interval of neutralino masses which are cosmologically favoured. We quantify the effect of coannihilations and the neutralino mass bounds. (C) 2005 Elsevier B.V. All rights reserved.

Abstract
We have made a very accurate calculation of the relic density of neutralino dark matter in the minimal supergravity framework. This calculation includes all so-called coannihilations and it uses the DarkSUSY package. In agreement with earlier analyses, we find that coannihilations have a huge effect on the density and this extends the interval of neutralino masses which are cosmologically favoured. We quantify the effect of coannihilations and the neutralino mass bounds. (C) 2005 Elsevier B.V.
