| dc.description | The cold plus hot dark matter (CHDM) model is arguably the best theory we currently have for a consistent description of the observed large scale structure formation. This is especially true if the primordial density fluctuations are assumed to be essentially scale invariant, in which case a mixture with 20-25 % HDM, 5- 10 % baryons, and the rest in CDM correctly predicted (in 1989) the quadrupole anisotropy measured a few years later by the COBE satellite. After a brief historical introduction, we present a model of supersymmetric inflation in which the CHDM model is neatly realized with a spectral index n= 0.98, while the dark matter consists of a few eV `tau' neutrino and the LSP (essentially the `bino'). We also provide a comparison of this model against the observations. | |
