A Dark Matter WIMP That Can Be Detected and Definitively Identified with Currently Planned Experiments

Abstract

A recently proposed dark matter WIMP (weakly interacting massive particle) has only second-order couplings to gauge bosons and itself. As a result, it has small annihilation, scattering, and creation cross-sections, and is consequently consistent with all current experiments and the observed abundance of dark matter. These cross-sections are, however, still sufficiently large to enable detection in experiments that are planned for the near future, and definitive identification in experiments proposed on a longer time scale. The (multi-channel) cross-section for annihilation is consistent with thermal production and freeze-out in the early universe, and with current evidence for dark matter annihilation in analyses of the observations of gamma rays by Fermi-LAT and antiprotons by AMS-02, as well as the constraints from Planck and Fermi-LAT. The cross-section for direct detection via collision with xenon nuclei is estimated to be slightly below 10−47 cm2, which should be attainable by LZ and Xenon nT and well within the reach of Darwin. The cross-section for collider detection via vector boson fusion is estimated to be ∼1 fb, and may be ultimately attainable by the high-luminosity LHC; definitive collider identification will probably require the more powerful facilities now being proposed.

“…Nowadays, the experimental search for dark matter is to let the expected dark particles collide with the particles in the instrument [42][43][44][45][46]. The preconceived dark particles are thought to have PKE.…”

“…It is also worth mentioning that the tree-level interactions between the dark matter and the SM in simplified models can generate loop processes which may still induce detectable signals. These can play important roles in future of direct detection experiments such as the one proposed here [285][286][287][288][289][290][291][292][293][294][295][296][297][298][299][300][301][302][303].…”
