Abstract

In the context of the unconfined-color gauge theory, we study whether the color gluons may be relatively light and yet have escaped experimental detection. We find that photoproduction experiments, which provide the most severe restrictions, are not yet quite sensitive enough to exclude the existence of color gluons with a mass in the region of 1.1 to 1.8 GeV, but a modest increase in sensitivity in such experiments should enable one to settle this question one way or the other. A gluon mass below 1 GeV appears to be difficult to reconcile simultaneously with the observed value of $g - 2$ for the muon, experimental upper limits on newcharged-particle lifetimes, and photoproduction experiments. A mass between 2 and 3 GeV appears to be incompatible with date from $e^{+} e^{-}$ annihilation and photoproduction. An explicit search for a narrow neutral gluon ( $Γ \sim 1$ to few MeV) in $e^{-} e^{+}$ annihilation in the energy range 1.1 to 1.8 GeV, which (if it exists) will exhibit itself as a prominent peak in $σ_{total}$ , should provide a more definitive answer to the question of whether observable gluons exist with such light mass.
