  We study the transition widths of $\Upsilon(10753)$ and $\Upsilon(11020)$
into standard bottomonium under the hypothesis that they correspond to the two
lowest laying $1^{--}$ hybrid bottomonium states. We employ weakly coupled
potential NRQCD an effective filed theory incorporating the heavy quark and
multipole expansions. We consider the transitions generated by the leading
order and next-to-leading order singlet-octet operators. In the multipole
expansion the heavy quark matrix elements factorize from the production of
light-quark mesons by gluonic operators. For the leading order operator we
compute the widths with a single $\pi^0$, $\eta$ or $\eta'$ in the final state
and for the next-to-leading operator for $\pi^+\pi^-$ or $K^+K^-$. The
hadronization of the gluonic operators is obtained, in the first case, from the
axial anomaly and a standard $\pi^0-\eta-\eta'$ mixing scheme and, in the
second case, we employ a coupled-channel dispersive representation matched to
chiral perturbation theory for both the $S$ and $D$ wave pieces of the gluonic
operator. We compare with experimental values and semi-inclusive widths. Our
results strongly suggest that $\Upsilon(11020)$ is indeed a hybrid bottomonium
state.
