[en] The novel measurements of the γ*N → Δ(1232) Coulomb quadrupole form factor in the range Q² = 0.04-0.13 GeV² changed the trend of the previous data. With the new data the electric and Coulomb form factors are both in remarkable agreement with estimates of the pion cloud contributions to the quadrupole form factors at low Q². The pion cloud contributions to the electric and Coulomb form factors can be parametrized by the relations G_E ∝ G_En/(1 + (Q²)/(2M_Δ(M_Δ-M))) and G_C ∝ G_En, where G_En is the neutron electric form factor, and M, M_Δ are the nucleon and Δ masses, respectively. Those parametrizations are in full agreement with Siegert's theorem, which states that G_E = (M_Δ-M)/(2M_Δ)G_C at the pseudothreshold, when Q² = -(M_Δ-M)², and improve previous parametrizations. Also a small valence quark component estimated by a covariant quark model contributes to this agreement. The combination of the new data with the new parametrization for G_E concludes an intense period of studying the γ*N → Δ(1232) quadrupole form factors at low Q², with the agreement between theory and data.
