[math-fun] SUSY, hence string theory, experimentally refuted?

SUSY explains many things theoretically, but there is absolutely no experimental evidence for it to date. On Tue, Nov 13, 2012 at 6:51 PM, Warren Smith <warren.wds@gmail.com> wrote:

more web sources pontificate re this: http://www.terascale.de/news/alliance_newsletter/june_2012/e130156/index_eng... http://www.newscientist.com/article/dn22492-rare-particles-decay-confounds-h... (a) Apparently SUSY is not destroyed by this experimental finding, it is merely "strongly confined in parameter space"; (b) however the confinement is into a region which also happens to be compatible with plain standard model without supersymmetry, which would seem pretty darn peculiarly unlucky if SUSY is true, but expected if SUSY is false; (c) further this whole ball of wax is based on observing only a single decay, which seems a bit much, even for hype-happy physicists; and I would think/hope that they'd wait until they see about 10... which ought to happen if run experiment longer.
