As astronomical observations and their interpretation improve, the case forcold dark matter (CDM) becomes increasingly persuasive. A particularlyappealing version of CDM is a weakly interacting massive particle (WIMP) with amass near the electroweak scale, which can naturally have the observed relicabundance after annihilation in the early universe. But in order for a WIMP tobe consistent with the currently stringent experimental constraints it musthave relatively small cross-sections for indirect, direct, and colliderdetection. Using our calculations and estimates of these cross-sections, wediscuss the potential for discovery of a recently proposed dark matter WIMPwhich has a mass of about 70 GeV/c$^2$ and only second-order couplings to W andZ bosons. There is evidence that indirect detection may already have beenachieved, since analyses of the gamma rays detected by Fermi-LAT and theantiprotons observed by AMS-02 are consistent with 70 GeV dark matter havingour calculated $\langle \sigma_{ann} v \rangle \approx 1.2 \times 10^{-26} $cm$^3$/s. The estimated sensitivities for LZ and XENONnT indicate that theseexperiments may achieve direct detection within the next few years, since weestimate the relevant cross-section to be slightly above $10^{-48}$ cm$^2$.Other experiments such as PandaX, SuperCDMS, and especially DARWIN should beable to confirm on a longer time scale. The high-luminosity LHC might achievecollider detection within about 15 years, since we estimate a collidercross-section slightly below 1 femtobarn. Definitive confirmation should comefrom still more powerful planned collider experiments (such as a futurecircular collider) within 15-35 years.
