Ro-vibrational spectroscopy of the hydrogen molecular ions H2+ and HD+ is a promising path for fundamental constants metrology. It could improve the current knowledge of the proton-to-electron mass ratio and contribute to resolving the current discrepancy on the proton charge radius and/or Rydberg constant. Very precise predictions of the transition frequencies, taking high-order QED...

Molecular hydrogen is the smallest neutral molecule and the most abundant molecular species in the Universe. High-resolution spectroscopic studies of this benchmark system can serve as a test for various directions in the exploration of new physics. Several of those have been pursued: - The search for a variation of the proton-electron mass ratio in earlier phases of the Universe; this is...
