Abstract

The scaling violations of the structure functions F2, xF3, and {Mathematical expression}, as measured in deep-inelastic neutrino-nucleon scattering at high hadron mass W, have been compared with the predictions of QCD and other candidate field theories of strong interactions. Non-asymptotically free theories with scalar and vector gluons are incompatible with the data. This leaves QCD as the only field theory that gives a consistent description of all the observed scaling violations. The data do not, however, permit a sensitive test of the existence of the gluon self-coupling.
