dc.description.abstractCosmic topological defects in a wide class of supersymmetric theories can simultaneously be sources of Higgs bosons of mass~supersymmetry breaking scale~TeV, as well as superheavy gauge bosons of mass~η>>1 TeV, η being the gauge symmetry breaking scale. Decay of these Higgs and gauge bosons may contribute significantly to the extragalactic diffuse γ-ray background (EDGRB) above ~10 GeV and explain the highest energy cosmic ray (HECR) flux above ~10/Sup11 GeV, respectively. Cosmic strings with η much above 10/Sup14 GeV overproduce both HECR and EDGRB, and hence are ruled out, if massive particle radiation is their dominant energy loss mechanism.en
