Predictions for Bottomonium from a Relativistic Screened Potential Model

In this work, a comprehensive analysis of the mass spectra and decay properties of bottomonium states using a relativistic screened potential model is carried out. The mass spectrum, decay constants, $E1$ transitions, $M1$ transitions, and annihilation decay widths are evaluated. The interpretation of $\mathrm{{\rm Y}}(10355)$, $\mathrm{{\rm Y}}(10580)$,$\mathrm{{\rm Y}}(10860)$, and $\mathrm{{\rm Y}}(11020)$ as $S-D$ mixed bottomonium states are analysed. The $\mathrm{{\rm Y}}(10355)$ state is considered to be $3S-2D$, $\mathrm{{\rm Y}}(10580)$ state is considered to be $4S-3D$ mixed state, the $\mathrm{{\rm Y}}(10753)$ is obtained as purely ${\mathrm{{\rm Y}}}_1(3D)$ bottomonium state, and the $\mathrm{{\rm Y}}(10860)$ and $\mathrm{{\rm Y}}(11020)$ are deemed to be $5S-4D$ mixed states.
