Query: Strong decays of the lowest bottomonium hybrid within an extended
  Born-Oppenheimer framework   We analyze the decays of the theoretically predicted lowest bottomonium
hybrid $H(1P)$ to open bottom two-meson states. We do it by embedding a quark
pair creation model into the Born-Oppenheimer framework which allows for a
unified, QCD-motivated description of bottomonium hybrids as well as
bottomonium. A new $^{1}\!P_{1}$ decay model for $H(1P)$ comes out. The same
analysis applied to bottomonium leads naturally to the well-known $^{3}\!P_{0}$
decay model. We show that $H(1P)$ and the theoretically predicted bottomonium
state $\Upsilon(5S)$, whose calculated masses are close to each other, have
very different widths for such decays. A comparison with data from
$\Upsilon(10860)$, an experimental resonance whose mass is similar to that of
$\Upsilon(5S)$ and $H(1P)$, is carried out. Neither a $\Upsilon(5S)$ nor a
$H(1P)$ assignment can explain the measured decay widths. However, a
$\Upsilon(5S)$-$H(1P)$ mixing may give account of them supporting previous
analyses of dipion decays of $\Upsilon(10860)$ and suggesting a possible
experimental evidence of $H(1P)$.
