New limits to the infrared background: Bounds on radiative neutrino decay and on contributions of very massive objects to the dark matter problem

Abstract:

From considering the effect of γ γ interactions on recently observed TeV gamma-ray spectra, improved limits are set to the density of extragalactic infrared photons which are robust and essentially model independent. The resulting limits are more than an order of magnitude more restrictive than direct observations in the 0.025-0.3 eV regime. These limits are used to improve constraints on radiative neutrino decay in the mass range above 0.05 eV and to rule out very massive objects as providin...
