Antihydrogen spectroscopy and CPT symmetry

by Chris Rasmussen (CERN)

Thursday 28 Jul 2022, 15:00 → 16:00 US/Eastern

Antihydrogen - the antimatter equivalent of the hydrogen atom - is a unique platform for testing fundamental symmetries. In particular, CPT symmetry (Charge, Parity and Time) requires that the spectrum of antihydrogen be identical to its ordinary matter cousin. In the ALPHA experiment at CERN, antihydrogen atoms are synthesized and magnetically trapped to enable precise measurements and comparison to hydrogen. Recently, we have measured the 1S-2S transition with a relative error of just 2 parts in a trillion - the most precise direct measurement on an antimatter system to date.
