Phys. Rev. Lett. 82, 2254–2257 (1999)CPT and Lorentz Tests in Hydrogen and AntihydrogenReceived 20 July 1998; published in the issue dated 15 March 1999 Signals for CPT and Lorentz violation at the Planck scale may arise in hydrogen and antihydrogen spectroscopy. We show that certain 1S-2S and hyperfine transitions can exhibit theoretically detectable effects unsuppressed by any power of the fine-structure constant. © 1999 The American Physical Society URL:
