2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/44831We have searched for high Pt (>40 GeV/c) jet events in ppbar collisions at the Fermilab TEVATRON (S**1/2 = 1800 GeV/c2) which have large pseudo-rapidity differences between the jets and are consistent with zero particle production from the underlying event. Preliminary analysis indicates that a significant fraction of these events with "voids" are present.
