Axigluons in theϒsystem

Abstract
We consider the virtual effects of axigluons, octet gauge bosons present in chiral-color models, in the ϒ system. Specifically, we examine the decay ϒA*gqq¯g, where A* is a virtual axigluon, and the resulting contribution to the ϒ hadronic width, and set the limit MA>25 GeV.
