A Decaying Ultra Heavy Dark Matter (WIMPZILLA): Review of Recent Progress
Houri Ziaeepour
Abstract
Recent theoretical and observational motivations for existence of a decaying Ultra Heavy Dark Matter (UHDM) are reviewed. We show that present data from Ultra High Energy Cosmic Rays (UHECRs) and SN - Ia are compatible with a relatively short lifetime of UHDM.
