摘要：

We describe the pion electroproduction processes in the Delta(1232)-resonance region within the framework of chiral effective-field theory. By studying the observables of pion electroproduction in a next-to-leading order calculation we are able to make predictions and draw conclusions on the properties of the N -> Delta electromagnetic form factors.
