Nucleon form factors and light-front dynamics

;
The structure of electromagnetic and weak currents is investigated in a relativistically invariant model in which nucleons are considered as bound states of three light quarks in light-front dynamics. Magnetic moments and large momentum transfer asymptotics of the nucleon elastic form factors are calculated. The deep inelastic form factors are evaluated and their relation to the elastic-form-factor asymptotics is discussed. Sum rules and relations between neutrino electroproduction and scattering on nucleons are derived in the framework of the considered model. For many examples the model provides a good fit to the data but one of the sum rules leads to a contradiction.
