[en] Based on the non-relativistic QCD factorization scheme, we study the hadroproduction of the bottomonium states Υ(5S) and Υ(6S). We argue to search for them in the final states Υ(1S,2S,3S)π+π-, which are found to have anomalously large production rates at Υ(5S). The enhanced rates for the dipionic transitions in the Υ(5S)-energy region could, however, also be ascribed to Yb(10890), a state reported by the Belle collaboration, which may be interpreted as a tetraquark. The LHC/Tevatron measurements are capable of making a case in favor of or against the existence of Yb(10890), as demonstrated here. Dalitz analysis of the Υ(1S,2S,3S)π+π- states from the Υ(5S)/Yb(10890) decays also impacts directly on the interpretation of the charged bottomonium-like states, Zb(10600) and Zb(10650), discovered by Belle in these puzzling decays.
