Abstract

We report results from a study of hadronic transitions of the χ_bJ(nP) states of bottomonium at Belle. The P-wave states are reconstructed in transitions to the Υ(1S) with the emission of an ω meson. The transitions of the n=2 triplet states provide a unique laboratory in which to study nonrelativistic quantum chromodynamics, as the kinematic threshold for production of an ω and Υ(1S) lies between the J=0 and J=1 states. A search for the χ_bJ(3P) states is also reported.
