Continuous Operation of an Odd Parity Lorentz Invariance Test in Electrodynamics using a Microwave Interferometer

摘要

We present results from an odd parity test of Lorentz Invariance in electrodynamics, based on a rotating microwave interferometer with permeable material in one arm. The experiment has been operating continuously since September 2007. Results set a limit on the Standard Model Extension (SME) scalar Lorentz violating parameter, K{sub}(tr), of -0.8±3.6×10{sup}(-7).
