INSTANTON-INDUCED PRODUCTION OF QCD JETS

We consider the instanton contributions for the production of a gluon jet with large transverse momentum in QCD. We find that Mueller's corr ections corresponding to the rescattering of hard quanta are likely to remove the contributions of large instantons, making this cross secti on well defined. This observation generalizes the previous discussion of instanton effects in deep inelastic scattering and suggests that al l hard processes in QCD receive hard non-perturbative corrections from instantons of small size, of order rho similar to 1/(Q alpha(S)).
