  • A bstractThe CDF and D0 collaborations have observed a forward-backward asymmetry in $ t\overline{t} $ production at large invariant mass in excess of the standard model prediction. One explanation involves a heavy color octet particle with axial vector couplings to quarks (anaxigluon). We describe and contrast various aspects of axigluons obtained from the breaking of a chiral SU(3)L × SU(3)R gauge theory both from the standpoint of a string-inspired field theory and from a quiver analysis of… CONTINUE READING
