Improved estimates of the nuclear structure corrections in $\mu$D

Understand

We calculate the nuclear structure corrections to the Lamb shift in muonic deuterium by using state-of-the-art nucleon-nucleon potentials derived from chiral effective field theory.

• Our calculations complement previous theoretical work obtained from phenomenological potentials and the zero range approximation.
• The study of the chiral convergence order-by-order and the dependence on cutoff variations allows us to improve the estimates on the nuclear structure corrections and the theoretical uncertainty coming from nuclear potentials.
• This will enter the determination of the nuclear radius from ongoing muonic deuterium experiments at PSI.
