Description

The ALPHA experiment at CERN traps antihydrogen atoms and performs precision measurements to explore matter-antimatter symmetry. The 1s-2s transition in antihydrogen is one of the most highly sensitive measurements to CPT invariance; in ALPHA-3, its precision is limited by the motion of the trapped atoms. This presentation discusses the role of Lyman–α laser cooling in ALPHA-3, with the goal of improving the precision of the 1s-2s transition measurement.
