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.
Description
We would like to remark the very pleasant and intellectually stimulat- ing atmosphere of the meeting in Zakopane. We thank L. Glozman for useful conversations, and grants FPA 2008-00592/FPA, FIS2008-01323, CERN/FP /83582/2008, POCI/FP /81933/2007, /81913/2007 , PDCT/FP /63907/2005 and /63923/2005, Spain-Portugal billateral grant HP2006- 0018 / E-56/07, as well as the Fund for Scientific Research Flanders.
