Abstract:
The measurement of the Lamb shift in muonic hydrogen and the subsequent
emergence of the proton radius puzzle have motivated an experimental
campaign devoted other light muonic atoms, such as muonic deuterium and
helium. For these systems nuclear structure corrections are the largest
source of uncertainty and consequently the bottle-neck for exploiting
the experimental precision to extract the nuclear radii. Utilizing
techniques and methods developed in few-body nuclear physics, we have
been able to provide the so far most precise determination of nuclear
structure corrections due to a two-photon exchange diagram. I will
review our recent calculations for light muonic atoms, and present an
outlook for the future.
