dc.description.abstract	We provide a systematic assessment of the order-α5 nuclear contributions to the Lamb shift of muonic deuterium, including the accompanying radiative corrections due to vacuum polarisation, up to nextto-next-to-next-to-leading order (N3LO) within the pionless effective field theory (π/ EFT). We also evaluate higher-order corrections due to the single-nucleon structure, which are expected to be the most important corrections beyond N3LO. We find a correlation between the deuteron charge and Friar radii, which can be useful to judge the quality of charge form factor parametrisations. We refine the theoretical description of the 2γ -exchange contribution, especially in the elastic contribution and the radiative corrections, ameliorating the original discrepancy between theory and experiment in the size of 2γ -exchange effects. Based on the experimental Lamb shift of muonic deuterium, we obtain the deuteron charge radius, rd(μD) = 2.12763(13)exp(77)theory fm, which is consistent with (but less precise than) the value obtained by combining the H-D isotope shift with the muonic-hydrogen Lamb shift. The theory uncertainty is evaluated using a Bayesian procedure and is dominated by the truncation of the π/ EFT series.	en_GB
