Partner of η₂(1645) in the 1¹ D₂ Meson Nonet

In the qˉq ˉquark model, the states π₂(1670) and η₂(1645) are assigned as the 1¹D₂ meson nonet. The partner of state η₂(1645) needs further confirmation in the experiments. We employ the meson--meson mixing and the Regge trajectory methods to calculate the mass of the partner of state η₂(1645) to be 1879.8MeV and 1863± 24MeV respectively. We also calculate the strong decay width in the ³P₀ decay model. These predictions can be compared with experiments in the future.
