Supersymmetry and dark matter WIMPs from a new perspective

After decades of optimistic expectations, why is there still no evidence of supersymmetry or dark matter WIMPs? The combined results of our papers on a 70 GeV dark matter candidate [1,2] and a modified version of supersymmetry [3-5] potentially provide a unified explanation: Both the dark matter WIMP and sfermions belong to a new scalar boson sector with only second-order interactions, so that detection cross-sections are dramatically reduced for the dark matter candidate and experimental signatures are radically modified for superpartners. In particular, squarks and gluinos can radiate other particles, transform into other species of the same kind, and hadronize, but not decay in the usual sense. This means that two principal signatures of conventional SUSY are absent, and a shift to other signatures is required for collider detection if the present formulation is correct.
