Abstract

A study of the lateral development of jets of hadrons produced in electron-positron annihilation has been used to determine the strong coupling constant s. Data were obtained with the MAC detector at the SLAC e+e- storage ring PEP at s=29 GeV. Based on the parton calculations of Gottschalk and Shatz, a value for s of 0.1330.005(stat)0.009(syst) has been determined for string fragmentation, and 0.1120.008(stat)0.007(syst) for an independent-jet model. © 1989 The American Physical Society.
