Abstract
We observe that excited hadrons provide an opportunity to probe from experiment the power-law running of the quark mass in the mid infrared, while the condition m(k) < k remains valid. A relatively clean analysis is possible for the maximum spin excitations of the Delta baryons accessible at current experimental facilities such as ELSA and Jlab.
