Discrepancies in measurements of the QCD running coupling constant are
consistent with a new vector gauge boson coupling to baryon number with
strength aB~0.1. Upsilon decays constrain such a boson to have a mass greater
than about 35 GeV. It is difficult to observe such a boson in Z decays, e+e-
annihilation, or hadronic interactions.
