QED Corrections of Orders m*a*6 and m*a*6(m/M) for HD*+ Spin-Independent Rovibrational Transitions Beyond Born-Oppenheimer Approximation / Z.-X.Zhong, V.I.Korobov, [a.o.]. – Text : electronic // Physical Review A. – 2026. – Vol. 114, No. 3. – P. 032814. – URL: https://doi.org/10.1103/x5q9-pdcj. – Bibliogr.: 41.

The effective Hamiltonian of 𝑚⁢𝛼*6- and 𝑚⁢𝛼*6⁢(𝑚/𝑀)-order corrections for hydrogen molecular ions has been derived by Zhong et al. [Z.-X. Zhong, W.-P. Zhou, and X.-S. Mei, Phys. Rev. A 98, 032502 (2018)]; in this work we express the energy correction in the form of finite-value effective operators. The cutoff regularization scheme is used to determine the finite part of divergent operators of the leading-order recoil corrections. Numerical calculations of first-order contributions are performed in the Hylleraas basis set. Combining the second-order terms calculated in recent work [V. I. Korobov, J.-P. Karr, and Z.-X. Zhong, Mol. Phys. e2563023 (2025)], the 𝑚⁢𝛼6-order corrections for the fundamental rovibrational transition are obtained with an uncertainty three times smaller than in previous calculations.
