Query: Dispersive evaluation of the Lamb shift in muonic deuterium from chiral
  effective field theory   We merge the dispersive relation approach and the ab initio method to compute
nuclear structure corrections to the Lamb shift in muonic deuterium. We
calculate the deuteron response functions and corresponding uncertainties up to
next-to-next-to-next-to-leading order in chiral effective field theory and
compare our results to selected electromagnetic data to test the validity of
the theory. We then feed response functions calculated over a wide range of
kinematics to the dispersion-theory formalism and show that an improved
accuracy is obtained compared to that with the use of available experimental
data in the dispersive analysis. This opens up the possibility of applying this
hybrid method to other light muonic atoms and supplementing experimental data
with ab initio theory for kinematics where data are scarce or difficult to
measure with the goal of reducing uncertainties in estimates of nuclear
structure effects in atomic spectroscopy.
