High Mass-Energy Axions Excluded by LUX WIMP Search

I didn’t realize they would try this but I guess it’s a no brainer

I’m not listing all of the damn authors here though.


First searches for axions and axion-like particles with the LUX experiment, D.S. Akerib, et al., The LUX Collaboration, (7 April 2017)

The first searches for axions and axion-like particles with the Large Underground Xenon (LUX) experiment are presented. Under the assumption of an axio-electric interaction in xenon, the coupling constant between axions and electrons, gAe is tested, using data collected in 2013 with an exposure totalling 95 live-days × 118 kg. A double-sided, profile likelihood ratio statistic test excludes gAe larger than 3.5 × 10−12 (90% C.L.) for solar axions. Assuming the DFSZ theoretical description, the upper limit in coupling corresponds to an upper limit on axion mass of 0.12 eV/c2, while for the KSVZ description masses above 36.6 eV/c2 are excluded. For galactic axion-like particles, values of gAe larger than 4.2 × 10−13 are excluded for particle masses in the range 1-16 keV/c2. These are the most stringent constraints to date for these interactions.

I like my gravitational axions better, obviously, but they do have a good explanation of axions.

Our axions in this universe just happen to be super cool axions.

So what’s not to like about that? We’re so special.
