Description
Spin singlet toponium $\eta_t$ has been discovered at the LHC by using di-lepton angular correlation of semileptonically decaying top and anti-top quarks. We study di-lepton distribution from spin triplet toponium states, $\Theta$ and $\chi_t^1$, which are produced in $e^+e^-$ annihilation. We examine asymmetries in the dilepton distributions observable with beam polarization at the ILC.
