Study of $q\bar q \gamma$ and $gg\gamma$ Fragmentation Using Hadron Production In Radiative $\Upsilon$ Decays

ORAL

Abstract

Using data collected by the CLEO III detector at the Cornell Electron Storage Ring, we compare hadron production on the $\Upsilon$ resonances to that of the underlying continuum for the $\Lambda$, $p$, $\bar p$, $\phi$ and $f_2$. By examining radiative $\Upsilon$ decays versus photon tagged quark-antiquark events, we have a direct comparison of gluon versus quark fragmentation, allowing us to probe the differing manner in which gluons and quarks hadronize.
