Description

Inspired by the new resonance Y(10750), we calculate the masses and two-body OZI-allowed strong decays of the higher vector bottomonium sates within both screened and linear potential models. We discuss the possibilities of Υ(10860) and Y(10750) as mixed states via the S−D mixing. Our results suggest that Y(10750) and Υ(10860) might be explained as mixed states between 5S- and 4D-wave vector bb¯ states. The Y(10750) and Υ(10860) resonances may correspond to the mixed states dominated by the 4D- and 5S-wave components, respectively. The mass and the strong decay behaviors of the Υ(11020) resonance are consistent with the assignment of the Υ(6S) state in the potential models.
