Summary
Both CDF and D0 at Tevatron reported the
measurements
of forward-backward asymmetry in top pair production,
which showed possible deviation from the standard
model
QCD prediction. We'll show that a new color-octet
massive
vector boson with mass just above twice that of top
quark
can simultaneously account for the asymmetry and
differential distribution $d\sigma/dM_{t\bar t}$ in top
pair
production, without conflict with other measurements.
The
new particle can be discovered and studied at the more
powerful Large Hadron Collider.
