Abstract
The spin precession frequency of muons stored in the storage ring has been analyzed for evidence of Lorentz and violation. Two Lorentz and violation signatures were searched for a nonzero and a sidereal variation of . No significant effect is found, and the following limits on the standard-model extension parameters are obtained: ; ; and the 95% confidence level limits and .
