Abstract

We show that the idea that CDM are decaying superheavy particles which produce UHECR with energies beyond the GZK cutoff may simultaneously solve the problem of subgalactic structure formation in CCDM model. In particular, the Kuzmin-Rubakov's decaying superheavy CDM model may give an explanation to the smallness of the cosmological constant and a new thought to the CDM experimental search.
