A Tension between recent dark matter results and Lux-Xenon?

    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:

    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. :)
