25th High-energy physics international conference on quantumchromodynamics

Abstract: Belle II offers unique possibilities for the discovery and interpretation of exotic multiquark combinations to probe the fundamentals of QCD. Several quarknium(-like) states and exclusive B decays to charmonium(-like) states were rediscovered with currently available data at Belle II. Belle II collected data samples near 10.75 GeV to study Υ(10753) on peak and B(*)B(*)bar decomposition.
