This new paper, http://www.arxiv.org/PS_cache/hep-ph/pdf/0506/0506190.pdf [Broken], contains a stringy explanation of the latest unexplained difference, of order 31X10^-10, in the anomalous muon magnetic moment. The explanation is based on the Randall-Sundrum brane-world model, using a particular ("ADD") specialization of it. The author, Konosuke Sawa, assumes the brane the standard model physics lies on can fluctuate, and therefore stretch, and that these fluctuations are stationary in time (this is his big extra assumption). Then he can calculate the contribution of the stretching to the AMM spread of the muon, and Lo! it matches pretty well. There is an undetermined parameter that he could tune to make it exact, but the parameter has cosmological consequences too, which constrain it. In any case he gets the 10^-10 right.(adsbygoogle = window.adsbygoogle || []).push({});

By itself this isn't falsifiable, since it's a proposed explanation, not a prediction. But in his conclusion Sawa proposes to apply the same method to Lorentz symmetry breaking, an unresolved question at this time. There is a possible chance for him to make a prediction that could later be checked at LHC.
