Muonium fine structure: theory update, tests of Lorentz violation and experimental prospects

Philipp Blumer, Svenja Geissmann, Arnaldo J. Vargas +3

We review the status of the QED calculations for the muonium $2S_{1/2}-2P_{3/2}$ energy interval and provide the updated theoretical value of $9874.357\pm 0.001\mathrm{MHz}$. Addi…
