Abstract
We have studied the energy-energy correlation in e+e- annihilation into hadrons at s =29 GeV using the Mark II detector at the SLAC storage ring PEP. We find to O(s2) that s=0.1580.0030.008 if hadronization is described by string fragmentation. Independent fragmentation schemes give s=0.100.14, and give poor agreement with the data. A leading-log shower fragmentation model is found to describe the data well. © 1988 The American Physical Society.
