Considerable motivation comes from the close analogy between instanton-induced B+L violation in electroweak processes and effects of QCD-instantons in deep inelastic scattering. We concentrate on the high multiplicity final state structure, reminiscent of an isotropically decaying “fireball”. A set of experimental isolation criteria is proposed. They serve to further enhance the striking event signature without significantly suppressing the expected rates.

The main aspects are inclusion of initial-state polarization as an analysing tool; a thorough investigation of e/sup +/eâ» yield W/sup +/Wâ», more precisely of compositeness-motivated deviations from the Standard
