Query: Top quark forward-backward asymmetry and charge asymmetry in left-right
  twin Higgs model   In order to explain the Tevatron anomaly of the top quark forward-backward
asymmetry $A_{FB}^t$ in the left-right twin Higgs model, we choose to give up
the lightest neutral particle of $\hat{h}$ field as a stable dark matter
candidate. Then a new Yukawa interaction for $\hat{h}$ is allowed, which can be
free from the constraint of same-sign top pair production and contribute
sizably to $A_{FB}^t$. Considering the constraints from the production rates of
the top pair ($t\bar t$), the top decay rates and $t\bar{t}$ invariant mass
distribution, we find that this model with such new Yukawa interaction can
explain $A_{FB}^t$ measured at the Tevatron while satisfying the charge
asymmetry $A_{C}^t$ measured at the LHC.Moreover, this model predicts a
strongly correlation between $A_{C}^t$ at the LHC and $A_{FB}^t$ at the
Tevatron, i.e., $A_{C}^t$ increases as $A_{FB}^t$ increases.
