Abstract
We discuss recent results from CLAS on electromagnetic resonance transition amplitudes and their dependence on the distance scale (). From the comparison of these results with most advanced theoretical calculations within QCD-based approaches there is clear evidence that meson-baryon contributions are present and important at large distances, i.e. small , and that quark core contributions dominate the short distance behavior.
