Antihydrogen Physics at ALPHA/CERN
Abstract
Cold antihydrogen has been produced at CERN (Amoretti et al. (Nature, 419, 456 (2002)), Gabrielse et al. (Phys. Rev. Lett. 89, 213401 (2002))), with the aim of performing a high-precision spectroscopic comparison with hydrogen as a test of the CPT symmetry. Hydrogen, a unique system used for the development of quantum mechanics and quantum electrodynamics, has been continuously used to produce high-precision tests of theories and measurements of fundamental constants and can lead to a very sensitive search for CPT violation. After the initial production of cold antihydrogen atoms by the ATHENA group, the ALPHA Collaboration (http://alpha.web.cern.ch/) has set forth on an experiment to trap and perform high-resolution laser spectroscopy on the 1S-2S transition of both atoms. In this contribution, we will review the motivations, goals, techniques, and recent developments towards this fundamental physics test. We present new discussion on predicted lineshapes for the 1S-2S spectroscopy of trapped atoms in a regime not discussed before.
Résumé
Nous avons produit de l’anti-hydrogène au CERN (Amoretti et al. (Nature, 419, 456 (2002)), Gabrielse et al. (Phys. Rev. Lett. 89, 213401 (2002))), pour faire des comparaisons spectroscopiques de haute précision avec l’hydrogène dans le cadre d’un test de la symétrie CPT. L’hydrogène, qui a joué un rôle unique dans le développement de la mécanique quantique et de l’électrodynamique quantique, a été utilisé continuellement dans des tests de haute précision des théories et des mesures des constantes fondamentales et peut nous conduire à une recherche très précise de la violation CPT. Après que le groupe ATHENA ait produit l’anti-hydrogène froid, l’équipe ALPHA (http://alpha.web.cern.ch/) a développé un montage pour piéger les deux types d’atome et faire des mesures de spectroscopie laser de haute précision des transitions 1S-2S dans les deux types d’atomes. Nous passons ici en revue les motivations, les buts, les techniques et les développements récents de ce test fondamental en physique. Nous présentons de nouvelles idées sur la forme des lignes en spectroscopie 1S-2S pour des atomes piégés dans un régime qui n’a pas encore été discuté.
