Measurement of pi0 fragments from jets produced in pp collisions at the CERN ISR

The jet fragmentation function into pi /sup 0/, f(z) has been measured using the away side high p/sub t/ pi /sup 0/ 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 a...

description The jet fragmentation function into pi /sup 0/, f(z) has been measured using the away side high p/sub t/ pi /sup 0/ 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/z/sup 3/ up to z approximately=1, but deviates sharply from it for z >or=1. Possible explanations of this effect are the single particle fragmentation mode of the quark or gluon jet, or quark fusion. (15 refs).
