A nonlocal quark model is described. Quarks are described by a virton field, existing as virtual states only. Hadrons are described by standard quantized fields and have experimentally observable masses. Hadrons are bound states of quarks. The model satisfies all axioms of relativistic quantum field theory and does not contain ultraviolet divergences. Hadron-quark interaction Lagrangians are introduced. The strong, electromagnetic, and weak decays of the pseudoscalar and vector mesons as well as the baryon octet and decuplet are considered. The model contains only two free parameters, which characterize the quark field. Good agreement with the experimental data is obtained.
