Inspired by the new resonance $Y(10750)$, we calculate the masses andtwo-body OZI-allowed strong decays of the higher vector bottomonium sateswithin both screened and linear potential models. We discuss the possibilitiesof $\Upsilon(10860)$ and $Y(10750)$ as mixed states via the $S-D$ mixing. Ourresults suggest that $Y(10750)$ and $\Upsilon(10860)$ might be explained asmixed states between $5S$- and $4D$-wave vector $b\bar{b}$ states. The$Y(10750)$ and $\Upsilon(10860)$ resonances may correspond to the mixed statesdominated by the $4D$- and $5S$-wave components, respectively. The mass and thestrong decay behaviors of the $\Upsilon(11020)$ resonance are consistent withthe assignment of the $\Upsilon(6S)$ state in the potential models.

Canonical interpretation of $Y(10750)$ and $\Upsilon(10860)$ in the $\Upsilon$ family
