Comment on ``Test of constancy of speed of light with rotating cryogenic optical resonators''
Résumé
A recent experiment by Antonini [Phys. Rev. A 71, 050101 (2005)] set new limits on Lorentz violating parameters in the framework of the photon sector of the standard model extension, kappa˜e-ZZ , and the Robertson-Mansouri-Sexl framework, beta-delta-1/2 . The experiment had significant systematic effects caused by the rotation of the apparatus which was only partly analyzed and taken into account. We show that this is insufficient to put a bound on kappa˜e-ZZ , and that the bound on beta-delta-1/2 represents a fivefold, not tenfold, improvement as claimed.
