Three-body QED test and fifth-force constraint from vibrations and rotations of HD$^+$
Résumé
We present a parts-per-million test of quantum electrodynamics (QED) in the molecular hydrogen ion, improving on previous tests based on vibrational and rotational transitions by factors of 76 and 1.4, respectively. The test is performed following a unified statistical approach that also produces improved constraints on physics beyond the standard model. We furthermore show how individual constraints derived from the various degrees of freedom in and antiprotonic helium can be combined to enhance the sensitivity, thus ruling out “fifth forces” on the Ångstrom scale that are times weaker than the electromagnetic interaction.
