    "abstract": "Nucleon form factors are evaluated in the spacelike region in a light-front\nframework. Our phenomenological model is based on a relativistic formulation of\nthe Hamiltonian dynamics. The baryon dynamics is solved in the CMS with\nrelativistic kinetic energy, linearly rising confining potential and a residual\ninteraction based on instanton-induced forces, the so-called \u0027t Hooft\ninteraction. The wavefunctions of the model are used to compute the nucleon\nform factors in the impulse approximation. In spite of taking no\nphenomenological constituent quark form factor by the one-body electromagnetic\ncurrent, we obtain a very good description of all electromagnetic form factors\nfor momentum transfers up to -3 GeV^2. The effect of the \u0027t Hooft interaction\nis carefully examined in the model.",
