| 330 | _aA relativistic light-front quark model is used to describe both the elastic nucleon and nucleon-Roper transition form factors in a large Q² range, up to 35 GeV² for the elastic and up to 12 GeV² for the resonance case. Relativistic three-quark configurations satisfying the Pauli exclusion principle on the light-front are used for the derivation of the current matrix elements. The Roper resonance is considered as a mixed state of a three-quark core configuration and a molecular N+σN+σ hadron component. Based on this ansatz we obtain a realistic description of both processes, elastic and inelastic, in the sector of positive parity and show that existing experimental data are indicative of a composite structure of the Roper resonance. A useful generalization of this technique is suggested for description of negative parity nucleon resonances 1/2−,3/2−,5/2−1/2−,3/2−,5/2−.This work was supported by the RFBR-DFG Grant No. 16-52-12019, by the DFG Grants Nos.
