Abstract

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 → ff, gg, γγ, W⁺W^-, Z⁰Z⁰, Z⁰γ and Z⁰H decays are roughly estimated. It is found that tens of opposite-charge dilepton events from the η_t → W⁺W^- decay and hundreds of events from the η_t → Z⁰H → ℓ⁺ℓ^-H decay using the single Z⁰ boson tagging method are expected to be accessible. This estimation provides a reference for future experimental study on the η_t meson.
