String theorists betting against SUSY July 23, 2008Posted by dorigo in physics, science.

This post contains second-hand information, but I place it here anyways because a blog is also a record of things. So, I read with interest on Peter Woit’s blog a summary of the latest paper posted on the ArXiv by Bert Schellekens. Peter’s review is worth reading head to tail (I don’t know about the 80-something page long article), but I especially found interesting a quote from Schellekens’ paper, which says it as clear as one can make it:
With the start of the LHC just months away (at least, I hope so), this is more or less the last moment to make a prediction. Will low energy supersymmetry be found or not? I am convinced that without the strange coincidence of the gauge coupling convergence, many people (including myself) would bet against it. It just seems to have been hiding itself too well, and it creates the need for new fine-tunings that are not even anthropic (and hence more serious than the one supersymmetry is supposed to solve).
Be sure to get this right: he is a die-hard landscape-enthusiast string theorist. And he is saying he would bet against SUSY at the LHC.
With the CERN machine’s start just around the corner, things are indeed getting to some accumulation point -I myself, after having bet heavily (well, for my standards) against the observation of SUSY at LHC, am starting to think I might in the end turn out the happy loser.
What is worth mentioning and is my final prediction, however, is that as soon as protons will start hitting other protons in the head at 10 TeV this fall, we will slowly relax and realize it’s going to take a while before we can say anything from that mess of hadrons that is going to come out of the center of CMS and ATLAS every 25 nanoseconds.
