Description
Belle experiment performed a study of several multibody decays
of $B$ and $\Upsilon$-mesons with multidimensional phase-space
analysis of the final states. Such analysis allows to separate
contributions
of different intermediate states and determine their quantum numbers.
We present some recent results on $\bar{B}^0 \to D^{*+} \omega \pi^-$, $\bar{B}^0 \to
J/\psi K^-\pi^+$, $e^+e^- \to \Upsilon(nS) \pi^+\pi^-$,
$\Upsilon$(10860) $\to \Upsilon$(nS)$\pi^0 \pi^0$ decays as well as techniques which
were used for these analyses.
