Vote LUX, and give an underdog a chance

I’ve had a busy few weeks after getting back from America, so apologies for the lack of blogging! Some things I’ve been up to:
– Presenting my work on LUX to MPs at the Houses of Parliament for the SET for Britain competition. No prizes, but lots of interesting questions from MPs, for example: “and what can you do with dark matter once you find it?”. I think he was looking for monetary gain, so perhaps I should have claimed dark matter will be the zero-carbon fuel of the future!
– Supplementing my lowly salary by marking an enormous pile of undergraduate problem sheets and by participating in paid eye-tracking studies for both the UCL psychology department and a marketing company
– The usual work on analysing LUX data and trying to improve our sensitivity to low mass dark matter.
And on Saturday, I will be on a panel of “experts” (how this has happened I don’t know) giving a talk as part of the UCL Your Universe festival. The discussion is aptly titled “Light into the Dark: Mystery of the Invisible Universe”, and if you’re in London and interested in this sort of thing, you should come along. Free tickets are available here.

I will hopefully be back to posting more regularly now, but first, a bit of promotion!

Symmetry Magazine are running a competition to find “which physics machine will reign supreme” and you can vote right here.

Physics Madness: Symmetry Magazine’s tournament to find the champion physics experiment

The first round matches LUX with the LHC, and considering we are a collaboration of just over 100 (compared to CERN’s thousands of scientists) with nothing like the media coverage the LHC gets, we’re feeling like a bit of an underdog.
But you can’t just vote for us because we’re an underdog, so here are some reasons you should #voteLUX:

-For spin-dependent WIMP-nucleon scattering for WIMPs above ~8GeV, LUX is 10,000x more sensitive than the LHC (see figure below).
-LUX cost millions of dollars, the LHC cost billions.
-It’s possible to have an understanding of how LUX works in its entirety. The LHC is too big and has too many detectors for that!
-The LHC is 175m underground. LUX is 1,478m underground, over 8x deeper, and so is much better shielded from cosmic rays.
-The LHC has encountered problems both times it has tried to start up. LUX is running smoothly right now!
-I actually feel kind of bad now, because I like the LHC, so I will stop.

Dark matter sensitivity limits

Dark matter sensitivity limits, comparing LHC results to LUX in red. The x axis is the mass of the dark matter particle, and the y axis is its interaction probability. The smaller this number, the greater the sensitivity.

Anyway, if you fancy giving the world’s most sensitive dark matter detector a hint of a chance in it’s battle against the behemoth LHC, vote LUX. Let’s beat the system!

    Your talk on Saturday at Your Universe was brilliant. Don’t worry about the missing slides, that was a fault on the equipment. Well done !
