Planar events produced in hadron-proton collisions at 147 GeV/c and their jet-like structures

An analysis is presented of the production of jets in low-p t π±p,k+p,pp collisions at 147 GeV/c collected at Fermilab in the rapid cycling hydrogen bubble chamber hybrid spectrometer. It is shown that selected events are more planar than predicted by a cylindrical phase space, but that 3-jet and 4-jet like structures seen in the momentum flows are reasonably reproduced by the cylindrical phase space events subjected to the same mathematical manipulation required to build momentum flows.
