We emphasize a new class of high transverse momentum hadronlc collisions in which the entire energy of an incident meson is delivered into production of a pair of large l? jets at large angle, with no final state particles emerging along the beam axisc Simple two-body kinematics govern the reaction, with the longitudinal and transverse momentum of the second jet being specified uniquely in terms of those of the trigger jet. The QCD subprocess which mediates the collision icvclves the direct coupling of the incident meson, and it is normalized absoluteiy
