Following the possibility of a new mass scale at the 3 PeV knee energy of the cosmic ray energy spectrum, the author suggests that the mass for the dark matter particle should be 8.1 TeV, using GLMR supersymmetry theory . The author discusses the possibility of detecting such a signature in various observational facilities, gamma ray, neutrino and other underground detectors. An analysis of recent data from HESS yields a gamma ray peak at 7.6 +/- 0.1 TeV, providing observational evidence for a dark matter particle mass consistent with the theoretical prediction. The author also suggests that the observed discontinuity in the power law index in galaxy correlation functions is the knee energy counterpart in cosmology.
