Abstract

The spin precession frequency of muons stored in the (g-2) storage ring has been analyzed for evidence of Lorentz and CPT violation. Two Lorentz and CPT violation signatures were searched for a nonzero Δωa(=ωaμ+- ωaμ-) and a sidereal variation of ωaμ±. No significant effect is found, and the following limits on the standard-model extension parameters are obtained: bZ=-(1.0±1.1)×10-23GeV; (mμdZ0+HXY)=(1.8±6.0)×10-23GeV; and the 95% confidence level limits bμ+<1.4×10-24GeV and bμ-<2.6×10-24GeV.
