Tension between recent dark matter results and Lux-Xenon?

Click For Summary
SUMMARY

The forum discussion centers on the tension between recent dark matter findings from AMS-02, which suggest a Weakly Interacting Massive Particle (WIMP) near 80 GeV, and the negative results from the LUX and Xenon experiments. Key papers referenced include Arxiv 1610.03840 and 1704.08258. The discussion raises questions about whether this potential dark matter particle should have been detected in LUX and Xenon results and speculates on its visibility in the upcoming LZ experiment. Concerns are also expressed regarding the reliability of claims linking the signal to dark matter, particularly in light of alternative explanations involving pulsars.

How much tension between recent AMS-02 80 Gev dark matter and Lux-Xenon negative results?
Recent results ( Arxiv 1610.03840 and 1704.08258) suggest a WIMP dark matter particle near 80 Gev. See also https://phys.org/news/2017-05-possibility-cosmic-rays-due-dark.html

If this particle really exists, should we have seen it in recent negative results from Lux and Xenon?

Should we see it in forthcoming LZ experiment?

I'm not sure how this claim ties back to the LUX data, but I'm always leery of claims like this:

From the abstract: Intriguingly, this signal is compatible with the DM interpretation of the Galactic center gamma-ray excess.

For quite some time it's been known that pulsars could emit the same type of gamma signals from the core, so I take these types of claims with grain of salt, particularly when they assign a 4.3 sigma to the claim. :) I'd assume that they simply didn't try a 'model' with a lot of large pulsars near the core. :)
