An experiment to measure the anti-hydrogen Lamb shift — •Paolo Crivelli — ETH Zurich, Institute for Particle Physics, 8093 Zurich, Switzerland
The upcoming operation of the Extra Low ENergy Antiprotons (ELENA) ring at CERN, the upgrade of the anti-proton decelerator (AD), and the installation in the AD hall of an intense slow positron beam with an expected flux of 108 e+/s will open the possibility for new experiments with anti-hydrogen (H). In this talk we will present an experiment to measure the Lamb shift of H at the 100 ppm level. This will provide a test of CPT and the first determination of the anti-proton charge radius at the level of 10%.
