Quantumgravitymotivated Lorentzsymmetry tests with laser interferometers
Abstract
We consider the implications for laser interferometry of the quantumgravitymotivated modifications in the laws of particle propagation, which are presently being considered in attempts to explain puzzling observations of ultrahighenergy cosmic rays. We show that there are interferometric setups in which the Planckscale effect on propagation leads to a characteristic signature. A naive estimate is encouraging with respect to the possibility of achieving Planckscale sensitivity, but we also point out some severe technological challenges which would have to be overcome in order to achieve this sensitivity.
