Abstract

We study the instanton-induced cross section of hard gluon scattering in deep-inelastic kinematics. We find that the structure functions may possess numerically large nonperturbative contributions, which are related to Ringwald-type processes with the violation of chirality, and correspond to the exponential correction to the coefficient function in front of the parton distribution of the leading ...
