Abstracts
By combining the q_{0} infty method for asymptotic sum rules with P infty method of Fubini and Furlan, we relate the structure functions W_{2} and W_{1} in inelastic lepton-nucleon scattering to matrix elements of commutators of currents at almost equal times at infinite momentum. We argue that the infinite-momentum limit for these commutators does not diverge, but may vanish. If the limit is
nonvanishing, we predict W_{2}(,q^{2}) f_{2}( /q^{2}) and W_{1}(,q^{2}) f_{1}( /q^{2}) as and q^{2} tend to infty. Fro m similar
analysis for neutrino process, we conclude that at high energies the total neutrino-nucleon cross sections rise linearly with neutrino laboratory energy until nonlocality of the weak current-current coupling sets in. The sum of p and p cross sections is determined by the equal-time commutator of the Cabibbo current with its time derivative, taken between proton states at infinite momentum.
