  Recently, the Belle Collaboration has updated the analysis of the cross
sections for the processes $e^+ e^- \to \Upsilon(nS)\, \pi^+ \pi^-$ ($n = 1,\,
2,\, 3$) in the $e^+ e^-$ center-of-mass energy range from 10.52 to 11.02~GeV.
A new structure, called $Y_b (10750)$, with the mass $M (Y_b) = (10752.7 \pm
5.9^{+0.7}_{-1.1})$~MeV and the Breit-Wigner width $\Gamma (Y_b) = (35.5^{+17.6
+3.9}_{-11.3 -3.3})$~MeV was observed. We interpret $Y_b (10750)$ as a compact
$J^{PC} = 1^{--}$ state with a dominant tetraquark component. The mass
eigenstate $Y_b (10750)$ is treated as a linear combination of the
diquark-antidiquark and $b \bar b$ components due to the mixing via gluonic
exchanges shown recently to arise in the limit of large number of quark colors.
The mixing angle between $Y_b$ and $\Upsilon(5S)$ can be estimated from the
electronic width, recently determined to be $\Gamma_{ee} (Y_b) = (13.7 \pm
1.8)$~eV. The mixing provides a plausible mechanism for $Y_b (10750)$
production in high energy collisions from its $b \bar b$ component and we work
out the Drell-Yan and prompt production cross sections for $p p \to Y_b (10750)
\to \Upsilon (nS)\, \pi^+ \pi^-$ at the LHC. The resonant part of the dipion
invariant mass spectrum in $Y_b (10750) \to \Upsilon (1S)\, \pi^+ \pi^-$ and
the corresponding angular distribution of $\pi^+$-meson in the dipion rest
frame are presented.
