Recent Belle results on various hadronic transitions among bottomonia are presented. We observe transitions with the η and η′ meson at the ϒ(4S). Bottomonium production together with the η meson is also reported at the ϒ(10860). We study π+π−π0 transitions at the ϒ(10860) and ϒ(11020).

Hadronic transitions are important decay modes of heavy quarkonia and serve as an elegant probe for the internal structure. Several remarkable discoveries have been made to identify the conventional heavy quarkonia and to extract useful information about the so called “XYZ” exotic states. We studied the hadronic transitions of higher charmonia in the framework of our recently proposed effective model to create light meson(s) in heavy quarkonium transitions. In this contribution, we discuss our results for the charmonium-[Formula: see text] decays of higher [Formula: see text] and [Formula: see text] wave vector charmonia. We also discuss quantum number [Formula: see text] assignments for few experimentally observed charmoniumlike states.
