Prospects for detection of $\mathrm{{\rm Y}}(1D)\to \mathrm{{\rm Y}}(1S)\pi \pi$ via $\mathrm{{\rm Y}}(3S)\to \mathrm{{\rm Y}}(1D)+X$

At least one state in the first family of D-wave $b\bar{b}$ quarkonium levels has been discovered near the predicted mass of 10.16 GeV/$c^2$. This state is probably the one with J=2. This state and the ones with J=1 and J=3 may contribute a detectable amount to the decay $\Upsilon(1D) \to \Upsilon(1S) \pi \pi$, depending on the partial widths for these decays for which predictions vary considerably. The prospects for detection of the chain $\Upsilon(3S) \to \Upsilon(1D) + X \to \Upsilon \pi \pi + X$ are discussed.
