Resumo

In this work the author discusses the experimental consequences of the use of the color magnetism concept in nonrelativistic quark models of the nucleon and its resonances. It is found that recent prescriptions used by some authors to apply this model to calculate amplitudes for the photoproduction and electroproduction of the Δ(1232) resonance do not give satisfactory agreement with well-established experimental results for the γN → Δ or γvN → Δ processes. Some of the reasons for the disagreement are considered and an alternative approach is suggested.
