Colloquium Seminar: Testing Lorentz invariance: The most precise measurement of relativistic time dilation
Speaker: Gerald Gwinner, University of Manitoba
Location: Auditorium
Time: 14:00
I will present concluding results from a series of Ives-Stilwell-type experiments at the TSR and ESR heavy ion storage rings. Using collinear laser spectroscopy on Li+ ions stored at speeds ranging from 0.03 to 0.34 c, and achieving absolute frequency accuracies at the 10^(-10) level, we have verified the relationship between the velocity beta and the time dilation factor gamma to within +/- 2.3 x 10^(-9). This puts limits on Lorentz-violating test theories.
