Book Description
A sample of proton-proton collisions at .sqrt. s = 63 GeV with a (trigger) charged particle of transverse momentum in the range 4 to 12 GeV/c and vertical bar rapidity vertical bar 1 is studied. The events were obtained with the Axial Field Spectrometer at the CERN ISR (experiment R807). Preliminary results are reported from an investigation of the distribution of the transverse momentum vectors of the observed charged particles in the central rapidity region associated with the trigger particle. It is found that the pattern of transverse momentum vectors of the observed charged particles in the central rapidity region associated with the trigger particle. It is found that the pattern of transverse momentum vectors of the charged particles observed in a given event is strongly dependent on the amount of transverse energy which is carried by the associated charged particles observed in the event. When the transverse energy is large ( 10 GeV/c within vertical bar rapidity vertical bar
