Abstract: Several aspects of hadron physics are well described by a simple 5D effectivefield theory. Baryons arise in this scenario as -large- and thereforecalculable 5D skyrmions. We extend and refine the existing analysis of this 5Dsoliton, which is fairly non-trivial due to the need of numerical methods. Weperform the complete quantization of those collective coordinates which arerelevant for computing the static observables like the nucleon form factors. Wecompare the result with simple expectations about large-N c QCD and with theexperimental data. An agreement within 30% is found.
