Query: Pseudotensor meson family   The pseudoscalar tensor states, $\pi_2$, $\eta_2$, and $K_2$, are
systematically studied through the Okubo-Zweig-Iizuka- allowed two-body strong
decays, including both the observed states reported by the Particle Data Group
and the predicted states. Phenomenological analysis combined with the
experimental data not only can test the assignments to these discussed states,
but it can also predict more abundant information {on} their partial decay
widths, which is helpful in the experimental study of these observed and
predicted pseudotensor states.
