摘要：This review emphasizes the close analogy between hard QCD instanton- induced chirality violating processes in deep-inelastic scattering and electroweak instan- ton-induced baryon plus lepton number (B + L) violating processes in Quantum Flavor Dynamics (QFD). Recent information about QCD instantons, both from lattice sim- ulations and from the H1 experiment at HERA, can be used to learn about the fate of electroweak B+L violation at future high energy colliders in the hundreds of TeV regime, such as the projected Very Large Hadron Collider (VLHC). The cross-sections turn out to be unobservably small in a conservative ¯ducial kinematical region inferred from the above mentioned QCD{QFD analogy. An extrapolation { still compatible with lattice results and HERA { beyond this conservative limit indicates possible observability at VLHC.
