Abstract

We report preliminary results from a study of hadronic transitions of the χbJ (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 χbJ (3P) states is also reported.
