摘要:

In this report, I will present the current status of the low-mass axigluon. The axigluon is a massive, color octet, axial vector boson, predicted in, e.g., chiral color models and some technicolor models, with a mass of order the electroweak scale. Axigluons with a mass larger than about 125 GeV to nearly 1 TeV can be eliminated by di-jet production at hadron colliders like the TEVATRON, but a low-mass window exists that the di-jet search can not probe. &Ugr; decays can rule out axigluons with a mass up to 25 GeV, and low energye+e−(PEP and PETRA) can rule out axigluons with a mass up to 50 GeV using a measurement ofR. Top production at the TEVATRON disfavors a light axigluon. A measurement ofRat LEP strongly disfavors a light axigluon, and rules out an axigluon with mass <365 GeV. ©1999 American Institute of Physics.
