| contents | Inspired by the observation of the $η_{t}$ meson at the LHC and the promising prospect of the $η_{t}$ meson available at the approaching HL-LHC, branching ratios for the $η_{t}$ ${\to}$ $f\bar{f}$, $gg$, $γγ$, $W^{+}W^{-}$, $Z^{0}Z^{0}$, $Z^{0}γ$ and $Z^{0}H$ decays are roughly estimated. It is found that tens of opposite-charge dilepton events from the $η_{t}$ ${\to}$ $W^{+}W^{-}$ decay and hundreds of events from the $η_{t}$ ${\to}$ $Z^{0}H$ ${\to}$ ${\ell}^{+}{\ell}^{-}H$ decay using the single $Z^{0}$ boson tagging method are expected to be accessible. This estimation provides a reference for future experimental study on the $η_{t}$ meson. |
