Description

The large data sample accumulated by the Belle experiment at the KEKB asymmetric-energy $e^{+} e^{-}$ collider provides a unique opportunity to perform studies related to hadron spectroscopy utilising various production mechanisms. We report a search for $X(3872)$ in the two-photon process $e^{+} e^{-}\to e^{\pm} e^{\mp} J/\psi \pi^{+}\pi^{-}$ and a study of $\chi_{c2}(1P)\to J/\psi \gamma$ again in the two-photon process. A search for the transitions from $\Upsilon(4S,5S)$ to $\eta_b(1S)$ and $\eta_b(2S)$ with the emission of an $\omega$ meson is reported. We also cover other searches such as $\eta_{c2}(1D)$ in $B$ decays or studies of charmed baryons including the first measurement of branching fractions of $B\to \Lambda_{c} \Xi_{c}$ decays.
