Description
The Belle and Belle II experiments have collected a 1.6 ab sample of e+
e- collision data at centre-of-mass energies near the Y(nS) resonances.
This provides a unique opportunity to study conventional and exotic
hadrons that cannot be described by the standard q\bar{q} or qqq
valence quark configurations.
In this talk, we present recent studies of exotic hadrons from Belle
and Belle II experiments. In particular, we show recent results and
prospects from Belle II concerning the properties of Υ(10753), which
might be interpreted as exotic. In addition, we present evidence for an
excess of events near the mass of a charmed pentaquark state
𝑃𝑐𝑠(4459)0
and search for pentaquark states in Υ(1,2𝑆) inclusive decays, both
at Belle.
