Higher-order corrections to spin-orbit and spin-spin tensor interactions in hydrogen molecular ions: Theory and application to ${\mathrm{H}}_{2}^{+}$

Résumé

We consider higher-order corrections to hyperfine coefficients related to the spin-orbit and spin-spin tensor interactions in hydrogen molecular ions. The mα7ln(α)-order radiative correction is derived in the NRQED framework. We present complete numerical calculations, including as well the mα6-order relativistic correction, for the case of H2+. The theoretical uncertainty is reduced by more than one order of magnitude with respect to the Breit-Pauli level, down to a few ppm. We also compare our results with available rf spectroscopy data.
