Search for New Color-Octet Vector Particle Decaying to ttbar in ppbar Collisions at $\sqrt{s}=1.96$ TeV

The CDF Collaboration, T. Aaltonen

We present the result of a search for a massive color-octet vector particle, (e.g. a massive gluon) decaying to a pair of top quarks in proton-antiproton collisions with a center-o…
