Experimental signatures of a new dark matter WIMP

The dark matter WIMP proposed here has the following properties: (1)~Its mass is $\le 125$ GeV. (2)~It will yield the observed dark matter abundance if its mass is $\sim$~75~GeV. (3)~The cross-section for nuclear scattering is consistent with the limits from direct detection experiments, (4)~the cross-section for collider production is consistent with limits from the LHC, and (5)~the cross-section for annihilation is consistent with the general (multiple-channel) limits from gamma-ray observations of dwarf spheroidal galaxies. The mass and annihilation cross-section (through 29 different channels) are in agreement with (6)~analyses of the observations of gamma rays from the Galactic center by Fermi-LAT and (7)~analyses of the antiprotons observed by AMS-02 (with both supporting the hypothesis of WIMP annihilation). (8)~The most promising signature for collider detection appears to be missing transverse energy of $\gtrsim$ 150 GeV following creation through vector boson fusion. (9)~The best hope for direct detection is still Higgs exchange. (10)~The present dark matter particle and the lightest neutralino of supersymmetry (susy) can stably coexist in a multicomponent dark matter scenario. This new dark matter candidate results from an extended Higgs sector with or without susy.
