Abstract
The Belle II experiment at the SuperKEKB asymmetric $e^{+}e^{-}$ collider at KEK, Tsukuba, Japan, is recording data since 2018.
The expected high luminosity of $\mathcal{L}=8\cdot 10^{35}~$cm$^{-2}$s$^{-1}$ enables searches for yet unobserved exotic hadronic states in B-meson decays. We describe the search for a partner state of the $X(3872)$ at the $D^{*}\bar{D}^{*0}$ threshold.
The reconstruction of charmed mesons is tested with experimental data corresponding to an integrated luminosity of $504~$pb$^{-1}$
collected at the energy in the center of mass of $\Upsilon(4S)$ in 2018, and $2.62~$fb$^{-1}$ in 2019.
