Theory of the Lamb Shift in Muonic Deuterium?

摘要

We present new calculation of the Lamb shift (2P_(1/2)? 2S_(1/2)), fine splitting of the 2P state and hyperfine splitting of the 2S state in muonic deuterium (μd) using the quasipotential method in quantum electrodynamics. The vacuum polarization, nuclear structure, and recoil effects are calculated with the account of contributions of orders α~3, α~4, α~5, and α~6. The obtained numerical value of the Lamb shift 202.4139 meV can be considered as a reliable estimate for the comparison with forthcoming experimental data.
