The recent results of IceCube Neutrino Observatory include an excess of PeVneutrino events which appear to follow a broken power law different from theother lower energy neutrinos detected by IceCube. The possible astrophysicalsource of these neutrinos is still unknown. One possible source of suchneutrinos could be the decay of non-thermal, long-living heavy mass DarkMatter, whose mass should be $> 10^{6} \rm {GeV}$ and could have produced atthe very early Universe. They can undergo cascading decay via both hadronic andleptonic channels to finally produce such high energy neutrinos. Thispossibility has been explored in this work by studying the decay flux of theseDark Matter candidates. The mass and lifetime of such Dark Matter particleshave been obtained by performing a $\chi^2$ fit with the PeV neutrino data ofIceCube. We finally estimate the baryon asymmetry produced in the Universe dueto such Dark Matter decay.
