Description

The jet fragmentation function into π0, f(z) has been measured using the away side high psub(t) π0 or eta mesons as a measure of the jet momentum. The fragmentation function is found to have an excess of events near z approximately 1 compared with the exponential fall-off observed at lower z values. The data behaves like 1/z3 up to z approximately 1, but deviates sharply from it for z>=1. Possible explanations of this effect are the single particle fragmentation mode of the quark or gluon jet, or quark fusion. (Auth.)
