“…The ratio of Γ Kρ Γ πK * is about 1.04 − 1.13. The decay branch of Γ Kρ Γ πK * = 1.95 ± 0.25 is higher than the experimental value slightly when K * 2 (1870)was regarded as a meson of the 2 3 P 2 state and its mass is close to the experimental value Γ = 272 ± 24 +50 −15 MeV [4]. we can have a nice description of K * 2 (1870) on the mass spectrum and decay behaviors under the assignment of K * 2 (2 3 P 2 ).…”

In this work, the mass spectrum of the K * 2 meson family is analyzed by the modified Godfrey-Isgur model with a color screening effect approximating the kaon as a heavy-light meson system, two-body Okubo-Zweig-Iizuka allowed strong decay partial widths are calculated via the 3 P 0 model. This analysis gives us the structures and possible assignments of the observed K * 2 candidates especially K * 2 (1980). Additionally, prediction of some partial decay widths is made on the high excitations of K * 2 family. This study is crucial to establishing and searching for their higher excitations in the future.

The contributions for kaon pair from the intermediate states $\rho(1450)^+$ and $\rho(1700)^+$ in the decays of $B^+ \to \bar{D}^0 K^+ \bar{K}^0$, $B^0 \to D^- K^+ \bar{K}^0$ and $B_s^0 \to D_s^-K^+ \bar{K}^0$ are analyzed within the perturbative QCD factorization approach. The decay amplitudes for all concerned decays in this work are dominated by the factorizable Feynman diagrams with the emission of the kaon pair, and the charged $\rho$ mesons should be of great importance in the $KK$ channel of the related three-body $B$ decays. Besides, these quasi-two-body decays are CKM-favored and the relevant branching ratios are predicted in the order of $10^{-5}$, which are potential to be measured by experiments. It is also shown that the contributions of the subprocesses $\rho(1450, 1700)^+ \to KK$ for the three-body $B$ meson decays are considerable according to the total three-body branching fractions presented by Belle. Therefore, the decays $B^+ \to \bar{D}^0 K^+ \bar{K}^0$, $B^0 \to D^- K^+ \bar{K}^0$ and $B_s^0 \to D_s^-K^+ \bar{K}^0$ can be employed to study the properties of $\rho(1450)$ and $\rho(1700)$ in the LHCb and Belle-II experiments.

“…A comprehensive study of the strangeonium spectrum is useful to test the theoretical models and also in the search for light exotica (resonances that are not dominantly qq states, often with nonexotic quantum numbers). Strangeonia have been studied in different experiments, such as the study of the initial-state radiation [3][4][5][6][7] and ψð3686Þ decays [8][9][10][11], and photoproduction data [12][13][14][15]. However, the strangeonium spectrum is much less well understood, and only a few states have been established.…”
