Hadron production bye+e−annihilation at center-of-mass energies between 2.6 and 7.8 GeV. II. Jet structure and related inclusive distributions

Abstract

We present results on the jet structure observed in multihadronic events produced by $e^{+}{e}^{-}$ annihilation in the Mark I magnetic detector at SPEAR. The evidence for jet structure and the jet-axis angular distribution are reported. We give inclusive distributions of the hadrons in Feynman $x$, rapidity, and transverse momentum relative to the jet axis.
