Comment on "Evidence for supersymmetric dark matter annihilations into γ rays"

The evidence for supersymmetric dark matter annihilations presented by Strausz is based on both an analysis of data from the JACEE balloon-borne emulsion experiment which ignores systematic uncertainties and on a flawed analysis of background data from the Whipple gamma-ray observatory. When the latter analysis is corrected, it is found that there is no evidence for a peak in the 3.5-4.0 TeV regime in the Whipple data. Furthermore, were any such excess seen in the Whipple data, it would indicate a flux in gross conflict with the JACEE upper limits. It is therefore concluded that no evidence exists for an annihilation Line due to supersymmetric dark matter. [S0556-2821(98)05404-6].
