Deep-inelastic scattering of leptons by hadrons and bremsstrahlung of gluons
Vainshtein A.I., Zakharov V.I., Novikov V.A., Shifman M.A.
A valent-quark model is proposed for the description of deep-inelastic scattering of leptons by hadrons within the framework of asymptotically free theories of strong interactions. The gluons are produced only as a result of bremsstrahlung of quarks and are absent in the initial state. The model describes satisfactorily the available data and makes it possible to formulate further predictions.
