A plausible explanation of $\mathrm{{\rm Y}}(10860)$

We show that a good description of the $\mathrm{{\rm Y}}(10860)$ properties, in particular the mass, the $e^{+}{e}^{-}$ leptonic widths and the ${\pi }^{+}{\pi }^{-}\mathrm{{\rm Y}}(ns)$$(n=1,2,3)$ production rates, can be obtained under the assumption that $\mathrm{{\rm Y}}(10860)$ is a mixing of the conventional $\mathrm{{\rm Y}}(5s)$ quark model state with the lowest $P-$ wave hybrid state.
