Experimental signatures of a new dark matter WIMP

Abstract

The WIMP proposed here yields the observed abundance of dark matter, and is consistent with the current limits from direct detection, indirect detection, and collider experiments, if its mass is ∼ 72 GeV/c 2 . It is also consistent with analyses of the gamma rays observed by Fermi-LAT from the Galactic center (and other sources), and of the antiprotons observed by AMS-02, in which the excesses are attributed to dark matter annihilation. These successes are shared by the inert doublet model (IDM), but the phenomenology is very different: the dark matter candidate of the IDM has first-order gauge couplings to other new particles, whereas the present candidate does not. In addition to indirect detection through annihilation products, it appears that the present particle can be observed in the most sensitive direct-detection and collider experiments currently being planned.

A next-generation liquid xenon observatory for dark matter and neutrino physics

“…The other cases are expected to be within the same order [314]. As shown in figure 12, this level of spin-independent cross section is well within the reach of the next-generation liquid xenon detector discussed here [311,336,337]. To avoid confusion, note that the LZ line in reference [311] corresponds to the sensitivity from the LZ design reports [108,338] instead of the goals shown reference [99].…”
